Dylan is a baker and the last job she had to do, was the wedding cake for her ex-boyfriend. So she's decided to enjoy it the most and have one crazy nightwith one of the hot guys invited. Enters Reese, the hot aaccountant she meets there and they immediately hit off and well, they have a pretty crazy night together.
But was supposedly to be a one night thing turns into something more and feelings they don't want to have, start to appear.
And as their romance evolves they'll have to figure out: Sweet, romantic and so, so sexy. I loved how this was a nice story with normal characters and no unnecessary drama. Other than that, this was a sweetly addictive story.
Writing Style: First person. Female POV.
Engaging and addictive with pretty sexy moments. Character Development: I loved Reese! Not only he was sexy as all hell, he was honest and a great guy. Dylan annoyed me at some moments but in general I liked her. The supportive characters were really good.
I loved how both of them had really nice group of friends. So HOT! View all 10 comments. I pretty much loathed this book. The characters were ridiculously immature. They were like foul mouthed teenagers who had nothing better to do than talk about their sex lives. There wasn't an ounce of depth to any of them. Also, let me make this perfectly clear, physical violence in a relationship is NOT sexy! It's unhealthy behavior.
Just because it's a woman doing the hitting and not the man it does not make it ok. The h in the story slapped the H numerous times and over things that she either I pretty much loathed this book. The h in the story slapped the H numerous times and over things that she either overreacted to or jumped to conclusions over and the author wants us to believe the H was simply ok with it and found it sexy. How sexy would it be if he slapped across the face?

My first thought was why would she be going to this wedding, well she owns a bakery and is in charge of the wedding cake. This has disaster written all over it, but instead of it being an epic Sweet Addiction is my favorite type of story, it is crazy sweet and crazy hot - I am a fan of the crazy!
This has disaster written all over it, but instead of it being an epic fail we get our first peek at just how funny Dylan is and what adventure she will be taking us on.
It was way too early to talk about dick sizes and which way they curve. Obviously Dylan was a fan as she decided to have her first wedding fling and had a little too much fun in the bathroom. This was the point I knew this was the story for me, because in the very beginning I found I loved Dylan's humor, spunk, and style. Then we have Reese and it was over, I loved how he was direct, sexy, and charming. Dylan and Reese fall into a friends with benefits type situation, but decide to be exclusive.
I say fall into as neither one of them really say what type of relationship they want, instead they make assumptions.
I loved watching their relationship build and unfold. These two are absolutely perfect for each other and I loved how they felt like real people. Their life was full of mishaps and misunderstandings, but it felt real to me.
I could empathize with Dylan and her thoughts, so even when things were on the rockier side I still enjoyed the story. Overall, this is a definite 5 star read for me. I love fun, sexy stories that also offer depth and of course hot sex. In a lot of stories I feel like we usually get one or the other, but this story delivered on all fronts. This is my first book by J. Daniels and I cannot wait to read more. Highly recommend!

I am questioning the trustworthiness of listopia now. It wasn't actually funny at all. I guess they were trying to be funny when they said things like the gay man had a "gay emergency".
When he asked why it was a gay emergency, she says they all are. Because he's gay? Can't gay people have straight emergencies or, oh I don't know, emergencies? It had the humor that bitchy, ca I went to the trusty listopia list and got me the first 10 or so entries in "funny romance" and this was one.
It had the humor that bitchy, catty girls who talk trashy have. You know, where everything becomes a sex joke? Eventually it gets really old and you feel like you need a shower to wash off the ick. The deal is that Dylan, our heroine, wants to hook-up with someone for wedding-sex at her ex-boyfriend's wedding. She talks a dirty game, but we later learn that she's never hooked-up with anyone anywhere before, and has never had an orgasm, and had only slept with one guy - the ex.
This all puts her into that "special virgin" category for the guy, Reese, who gets to alpha-out on the fact that he is the only one.
The man who OWNS her body. Blah blah blah Reese is a man-whore who has done more girls at a wedding than David's Bridal. But, when he finds Dylan, and screws her in the bathroom, he realizes she's special. Bathroom sex - the birthplace of many beautiful romances. My parents met that way, and my grandparents before them. It's so sweet! Let's celebrate our engagement with alcohol.
No, not drinks, I mean Purell. So, our couple decides to get into the worst, stupidest, most drama-laden relationship ever. Their relationship consists entirely of misunderstandings, angst, and her slapping his face - multiple times. It's ugly, but won't be ignored. Basically, what I'm saying is that this book is a trainwreck.
And, like most crazy people, I am indeed going to read the next book. And B. I can't look away. For a coherent and much better review, check out this one. But out of all the men she had to choose, she gets the man who is determined to convince her to give more. He wants more than just slutty wedding sex. There is no question that Reese wants more but all she wants to be is casual. Sweet Addiction is a funny sexy read with a complete cast: This was a complete feel good kinda read that is just what I needed after all the darker reads I've been consuming.
You can't go wrong with laughter, sweets and sex. View all 43 comments. Dylan is attending the wedding of her ex boyfriend.. Her ex is a total douche but she is there because she is the baker of the wedding cake..
And she is also looking for slutty wedding sex and free booze.. At the wedding she meets Reese.. You ask how? Well, how normal people meet nowadays.. She falls in his lap Thats exactly how it happened D Since she is only looking for a fling she suggests Reese.. Reese is soo sweet you really can't help falling in love with him. I have a sweet spot for panty thieves anyway: D But Dylan isn't sure if Reese is feeling the same for her.
Lets face it.. The story had some silly drama in it and in the end Even with the stupid drama I think this book is worth the read.
It was funny and light and totally steamy.. The Characters in this book were amazing and hilarious.. I really loved each of them It has a HFN ending..
I hope that Dylan learns to hear people out in book 2. I know drama, jealously and angst keeps a story thrilling. But it is possible to write books without unnecessary drama and break-ups in and it can be still an amazing and funny story.. I hope the author will focus on that in book 2. I don't want to read about how Dylan makes the same mistakes again And the minute she walks down her pew to sit she knows with whom she wants said sex, Reese Carroll.
Since when are accountants so freakin sexy? After a quick fuck in the men's bathroom which he leaves in a hurry with a mumbled sorry she's quite determined that this was the end of their adventure. That is until she is mistakenly informed that he is ma 3 Banana Muffin Stars If Dylan Sparks has to attend her stupid ex-boyfriend's wedding then by God, she's gonna get some hot, no strings attached sex.
That is until she is mistakenly informed that he is married and decides to confront him. Now they seem unable to stay away from each other but Dylan needs to keep the rules in place if she wants to walk away from this with her heart intact because she has been warned that Reese doesn't do serious. But if he doesn't do serious then why is he pushing the boundaries all the time?
The book started strong. There was plenty of hot sex and sweetness between Reese and Dylan but what stole the show was Dylan's friendhip with Juls and Joey.
The three of them together were the group of friends everyone wants. Fun, sweet and completely innapropriete most of the time. Joey, the gay best friend and bakery asssistant, seemed to have no filter whatsoever in the things that came out of his mouth. The scenes at Dylan's bakery were hilarious. And then the book became a cheese fest full of miscommunication. Silly arguements, ridiculous misunderstandings and a Dylan that went from awesome to pathetic. Instead of confronting Reese with how she felt about him and learning how he felt about her she just assumed that he wasn't there for the long run despite all the signs he gave that pointed to the opposite.
She took the word of a third person on the fact that Reese didn't do relationships and rolled with it. And Reese trying to pull of the "possessive Alpha male" didn't work for me. He just came across as an asshole. Especially the scene with the dress was ridiculous.
And Dylan just went ahead and forgave him like nothing happened. Like he didn't insinuate she was a slut. Thanks for the drama fest but no, thanks. Anyways, started great but didn't keep up that way More's the pity. It did have an awesome playlist though.
The author hit the mark with her music selection. View all 7 comments.
Mar 27, Alba and Her Secrets.. I've been wanting to read something by J. Daniels for a long time and when a fellow blogger friend recommended this series, I knew this was a great way to start. This will not be long. The best part? The man is sex on legs, dirty AF and just the best! One of my favorite book boyfriends, definitely! Loving this man and this series! View all 14 comments. The only negative thing I will say was there was just a little too much drama.
I could see it coming, the misunderstanding, the miscommunication, it just bugged me. Here is the gist… Dylan is a baker and a sexy one at that. She is heading off to her ex-boyfriends wedding with her gay guy friend and assistant Joey.
Dylan ends up meeting Reese.
After their rather clumsy meeting and a few cocktails, these two hookup for some scorching hot bathroom sex. Right… The sexual chemistry between these two was crazy. I loved it. The sexting, the little deliveries and all the sexy times had my heart racing. Yup and this is where the conflict comes into play and lack of communication which ultimately drove me batty. I loved them together but it just seemed that there was one misunderstanding after another. Reese was stepping up to the plate, trying to make more of their relationship but Dylan just had too much crap floating around in her head.
Overall it was an enjoyable read. It was funny, sexy and sweet. Her gay friend Joey was great. He had me laughing and rolling my eyes too. Her best friend Juls was great too. View all 36 comments.
Damiels Fans, Romance. I try really hard to be open to the Big Picture of books and most of the time I think I accomplish that goal. But every once in a while Now it was a personal thing for me I am saying from the beginning They were interesting There was a tight support system of friends and it all worked perfectly. The set up of meeting the main characters was cute and I was prepared for insta lust The attraction was there with the both of them The sexy times were fantastic My hiccup has to do with his use of an endearment for her There were also some issues with how she would assume negative stuff and then not accept his communication.
I understand So overall, a terrific story For more Reviews, Free E-books and Giveaways. View all 37 comments. Most of it felt like page filler porn without adding anything positive to the storyline.
For the late twenties and early thirties set, the immaturity level was off-balance and downright childish and juvenile. The book blurb and the cover attracted my attention to this one. Oh, the male lead was physically appealing , and I found myself more drawn to him as the story went along until I hit the silliness continually playing out between him and Dylan, who I had expected to be a favorite character.
She was not. I had a difficult time warming to Dylan, who drank and trash-talked more than her fair share. Her fetish for slapping Reese in the face every time she had a problem with him completely removed her from the radar. It seemed out-of-character for him. And once again, I ask the question: The major conflict here was pretty pathetic and overplayed. Communicate people! To be quite honest, I was quite content with leaving the story here.
Another book may be overkill.

The problem is the fighting of emotions as keeping he "casually monogamous" fling from getting serious. My faves: He is quite the perfect standard when it comes to 3. He is quite the perfect standard when it comes to book boyfriends. He is sweet, sexy, dominant and a swoon-worthy romantic. And, I cant forget the bff club Jules the gal pal, in love, hottie extraordinaire and Joey, the outrageously fun and perfect gay bf! The banter alone is worth the read.
My 2 second rant: I am not a fan of the dramatic face slap! My girl belted her love interest not once I lost count! I am all for the one time slap to someone being completely inappropriate and hurting you, but ummmm It just doesn't work for me. Reese was pretty amazing and if Dylan wasn't so damn horny and hot for him, he should not have taken her wrath!
Let's be real, it was Dylan who set the rules and it was Dylan who was always struggling with those rules! Ok ,so that's a me issue, and! Overall, I really enjoyed this book. In fact, until close to the end, it was a 5 star read for me. It had everything I love in a romance I really enjoyed the instant chemistry between Dylan and Reece. Dylan was hilarious and I found myself laughing out lout constantly at their banter.
They were so great together. There was little drama holding these two apart. So why only the 4 star? Well, like so many other books, the he Overall, I really enjoyed this book. Well, like so many other books, the heroine brought down the rating for me. She was beyond clueless to what was happening in her relationship with Dylan, which seemed out of character for her. And view spoiler [her not listening to reason for 3 whole months after overhearing Dylan say something???
I get that she was gutted over what she heard, but to not listen to explanations from anyone, even her friends??? Luckily, this did not detract from my overall enjoyment of the story. Loved loved loved Reece. Loved Dylan's potty mouth. Loved the friendship between Dylan, Joey and Juls. View all 4 comments. Well well well What an unexpected surprise this book was! When Dylan went to a wedding and wanted some slutty wedding sexy times She didn't know what exactly is going to happen.
No one follows the 'rules' When the girl is having the sex of her life and the time of her life You can guess how this played out A funny and sexy read with lots of Well well well A funny and sexy read with lots of cake eating pun intended and a sexy sexy man I can only picture as my fav boy!

Think about those Heroines, who are insane, crazy and kind of just silly, well Dylan is the opposite of that. I loved Dylan. I love how Daniels makes geeky number guy, crazy awesome and swoon worthly.
Reese is the guy you want to meet, fall in love with and make babies with. Dylan has crazy wedding sex with Reese in the bathroom and from there a non-serious relationship forms. Basically friends with benefits, but with only each other. Dylan tries really hard to keep her distance. She knows Reese is known to play the field and she can see that falling in love with Reese would be a very bad thing.
Reese just goes with the flow and I simply love it. I love how witty and funny the writing is. I read this in one sitting, it just simply perfect for me. If you looking for another Seduction and Snacks, then Sweet Addiction s for you. May 16, J. His hips move against my back as he pulls me again 'He has officially ruined all other men for me and I am perfectly fine with that. His hips move against my back as he pulls me against him, his hands slipping around my stomach. I close my eyes and feel his hands move up my rib cage, his thumbs brushing along the bottom of my breasts as I rub my ass against his crotch.
My pulse is hammering in my throat and I can feel my face heat up from the contact. His hands spin me and my chest presses against his. We continue to move against each other, his impressive erection digging into my stomach and my hands gripping tightly around his neck while he holds on to my hips.
If either of us were to move in slightly, we would be kissing. Were you dancing just for me? His eyes widen before he drops his hands from my waist and grabs my hand, pulling me away from the dance floor. Holy shit. This is it. I inwardly high-five myself as we move quickly between the guests.
I follow closely behind him, my heels preventing the faster walking I would have preferred as we move down the staircase and down the hallway that leads to the bathrooms. My chest is rising and falling rapidly and my nervous energy has kicked in, causing me to practically bounce on my feet. I lick my dry lips as he opens the door and smiles.
No fucking way. Come on. Now LIVE on all platforms! So hot and funny: May 17, Dilek VT marked it as dnf. Not feeling it! Too insta and too easy for me. View all 8 comments. After a few of my wonderful book friends recommended this book, and having spoken back and forth to this wonderful author, I decided to give Sweet Addiction a go.
Never having heard of this author before, I didn't know what sort of adventure I was in for so without reading the description and totally going by my friend's better judgement I practically went into this book blind and I came out seeing a different light I've always been into books with some angst.
I enjoy the whole 'characters wi After a few of my wonderful book friends recommended this book, and having spoken back and forth to this wonderful author, I decided to give Sweet Addiction a go. I enjoy the whole 'characters with issues and pretty much the messed-up' kind of books, but this blew me away in a completely different way, it was nothing I've ever read before. We first meet Dylan, who owns her own bakery and serves the best treats around. After coming out of a bad relationship she attends her, wait for it, EX-boyfriend's wedding.
There we get to meet her best friends Joey and Juls.
The second I got into this characters head I knew I was going to love her. She has a little something going for her that most heroines lack, she has the same dirty mind as a man. Are you kidding me with that voice?
Low and sweet, I can almost taste it.
My eyes quickly scan the rest of his face as Joey nudges me in the back, urging me to move forward. Fuck him. He can wait a second and allow me to marvel at this spectacle in front of me. He wants Dylan and Dylan want him, any way she can get him Did he just say that? Can I honestly respond to that?
Would he like it if i told him exactly what i want to say, which is i only want him to fuck my brains out at this wedding, or any wedding for that matter?.
From then on a type of 'friends with benefits' takes place and as much she Dylan tries not to, her feelings that's she's tired to lock away slowly want to come out, but the wall that's she built won't let that happen so Dylan does what's best for her heart, she stays behind that wall and is determined to keep that key locked away where she is safe.
The main thing I liked about Dylan's character was that no matter what she still expressed how much she wanted and cared for this man, she never once hid it from the reader, she just hid it from everyone else. She was scared of falling for this guy and getting her heart broken, like most girls in her position you can totally relate to her and that's what I loved about J. Daniel's writing and how she portraits Dylan, she made her a girl with real issues, she made her insecure, she made her human.
Plants have evolved protective measures to prevent herbivores from eating them. For example, some alkaloids that give the plant a bitter taste cause avoidance by most species in the animal kingdom 44 , Nonetheless, many animal species including hominids, as well as prehistoric humans, ingested lesser amounts of toxic substances and obtained benefits for their own survival Thus, a coevolution occurred as different traits were evolving in animals for the detection of caloric nutrients in foods i.
This would explain the chewing of cocaine or tobacco leaves by aborigines in the Americas allowing them better physical fitness to cope with fatigue and a better chance to catch prey or find food One could argue that, like our dependency on nutritive foods to survive, we were also partially dependent on certain toxic plants. What made them addictive? Analogous to nutrients, humans learned how to process these toxic plants, increasing their potency, as it is done in modern times, conferring drugs and foods with a salient rewarding response.
Ultimately, early in our evolution the ingestion of food or drugs emerged as positive reinforcement and evolved common neural circuits for reward, and that has not changed over time, owing to their sharing of similar neural mechanisms in addictive behavior 48 — Neural circuits for reward The limbic system consists of different brain regions engaged in various aspects of emotions. Historically, it included a bidirectional pathway between the hippocampus and the hypothalamus Over time, other structures have been added to the circuit including: the amygdala, the nucleus accumbens ventral striatum and the prefrontal cortex.
The functions of these structures are complex, and their diverse mechanisms of action are still being elucidated. To summarize, blocking the dopaminergic pathway between the VTA and the NAc inhibits instrumental responding for food and became the foundation of the dopamine DA hypothesis of reward DA in the NAc seems to have a preponderant role in the latter two components learning and incentive motivation and less in the former hedonics where the opioid and GABA system appear to play a stronger role 64 , For instance, original studies in the 's have shown that a lesion in the striatonigral DA pathway with 6-OH-dopamine provoked a profound aphagia and adipsia This finding was later corroborated in DA-deficient mice that also became hypoactive, aphagic, and adipsic Similarly, lever pressing for food pellets in animals increases DA release in the NAc 68 — 70 , however, not during rat chow free-feeding 70 , 71 suggesting that DA in the accumbens regulates instrumental learning.
Others have observed that accumbens DA increases during rat chow feeding only if rats were food deprived 72 , 73 or in the presence of palatable foods 74 — Interestingly, increased DA while eating highly palatable food wanes after repeated exposure 74 , 75 , 79 and this returns if palatable foods are switched to a different one 82 suggesting a role of this neurotransmitter in the NAc for novelty recognition.
Additionally, it has been shown that DA neurons respond to exposure of a novel food and if that novel food is paired with a cue, in a subsequent exposure, food alone will not induce neuronal firing while the cue alone does, suggesting that DA neurons are involved in conditioned learning 83 , Cue-invigorating food-seeking may be considered adaptive, but the maladaptive eating in the absence of hunger forms the basis for the FA hypothesis.
It has been shown that limited or intermittent access to highly palatable foods increase cue-reactivity to these foods, which has implications for the consequences of extreme dieting behavior in humans Another preponderance of evidence for the engagement of accumbens DA on feeding behavior comes from studies utilizing orexigenic peptides.
It is well known that some peptides in various brain sites are capable of initiating feeding behavior, for instance, paraventricular injection of galanin, ghrelin, or opioids will promote food intake even if rats are satiated 86 — These peptides, systemically or locally injected in the paraventricular nuclei, increased NAc DA 93 — It appears that accumbens DA plays more of a role in the anticipatory behavior than in the consummatory behavior.
Stomach-derived ghrelin has known action on orexigenic neurons in the hypothalamus, and receptors have been identified in the VTA, hippocampus, and amygdala 97 , Finally, pharmacological manipulation of the DA system has led to contradictory results. On the one hand, DA injected directly into the NAc is capable of increasing ingestive behavior , However, others have not been able to modify feeding behavior when specific DA agonists or antagonists were used , In part, these dissimilar findings show that it is very hard to propose that only one neurotransmitter or hormone is responsible for driving behavior.
Dysfunction of the dopaminergic system in obese subjects Investigators can identify animals that have propensity to become obese in a 5-day weight gain on a high-fat diet OP rats In these OP rats, a deficit of exocytosis mechanisms in the DA neuron was found, as well as a decrease in accumbal DA basal levels , Human studies using neuroimaging determined that obese patients had a lower sensitivity of the accumbens DA and a decrease in DA-D2 receptor availability , Variations in the DA-D2 gene have also been associated with impulsivity and a preference for smaller more immediate rewards compared to larger but delayed ones delay discounting It is possible that obese subjects compensate for the depressed DA basal levels by overeating palatable foods Conversely, optogenetical-induced increase in basal DA release inhibits consumption behavior How can these results be reconciled with other studies?
DA is released phasically and tonically with possible divergent tasks , Basal DA levels are likely to determine the tonic response of the system, thus could confer a complete opposite response.
Drugs of addiction and accumbens dopamine Most drugs of addiction activate the VTA-NAc pathway whether they are systemically injected or locally applied in the accumbens , Furthermore, drugs that increase DA release in the NAc are also self-administered — Thus, drugs of addiction, like food, increase DA release in the NAc, however with drugs, this increment occurs repeatedly every time it is given, compared to a decline in release observed with palatable food.
Blunted striatal DA and decreased DA-D2 receptor availability measured using radiotracers as binding potential relative to nonspecific binding have been repeatedly identified in position emission tomography PET scans of drug-addicted human subjects and is likely to be both a result and a cause of an addictive disorder Given the similarities in human PET scans between drug abusers and obese subjects , additional research is needed to identify neurobiological risk factors for addiction-like eating.
Animal studies suggest that overconsumption of each can be a predisposing factor for the other , They have an extensive axonal arborization and form synapses in the medium spiny output neuron It is known that anticholinergic antimuscarinic drugs were the first medications used in the treatment of PD antagonizing mainly M1 receptors , This indicates that DA normally exerts an inhibitory action on striatal ACh interneurons as demonstrated in rats In addition, L-dopa induced hyperlocomotion in DA-deficient mice is suppressed by cholinergic agonists Separately, anticholinergic drugs are abused probably by increasing DA activity in the striatum , thus, an antagonistic association probably exists between DA and ACh in the NAc and striatum.
ACh in the NAc appears to have a modulatory effect on feeding behavior. During free-feeding, ACh increased at the end of a meal 72 and during ingestion of a palatable food it reached a maximum after the animal stopped eating 79 , This increment disappeared in sham-fed animals that had a gastric fistula opened compared to controls with a closed gastric fistula Bilateral perfusion in the NAc of the indirect ACh agonist, neostigmine, reduced food intake in food-deprived animals Conversely, lesion of the cholinergic interneuron in the NAc with a specific toxin AF64A produced a significant increase in food intake All these results suggest that ACh in the NAc probably signals satiety.
Recently, researchers found that increasing the activity of the cholinergic interneuron in the NAc reduced palatable food consumption, lending support to the hypothesis that NAc-ACh acts as a stop signal What happens if food becomes an aversive stimulus?
Using a conditioned taste aversion paradigm, it has been shown that the aversive stimulus in this case saccharin would decrease DA release 78 while increasing ACh output Furthermore, injection of neostigmine indirect ACh agonist is sufficient to provoke a conditioned taste aversion Therefore, an increase in DA simultaneous to an increase in ACh release in the NAc signals satiety stop but if the change in release of these neurotransmitters is divergent decrease in DA and increase in ACh then the stimulus becomes aversive Taken together, animal feeding induces an initial and long-lasting increase in DA release followed by an increase in ACh output signaling satiation, making the animal feel satisfied DA release and stop the behavior ACh.
Effect of drugs of abuse and withdrawal on acetylcholine release in the NAc Drugs of addiction exert differential responses on the accumbens cholinergic interneuron. One could separate these drugs by their effect on feeding, for example, ACh release is decreased or not changed in the NAc if the drug increases food intake opioids, alcohol, benzodiazepines — while those that act as anorectic cocaine, amphetamine, nicotine produce the opposite effect, an increase in ACh release , — Moreover, cholinergic ablation in the NAc increased sensitivity to cocaine What is common for most drugs of addiction is that during drug withdrawal ACh is increased in the NAc , — , In addition, enhanced functioning of the ACh interneuron in the NAc prevents addictive behaviors for cocaine and morphine The augmented release of ACh in the NAc occurs simultaneously to a decrease in DA release , , , , identical to the response observed during a conditioned taste aversion.
What is the difference between food and drugs of addiction?
