For Smoking Cessation "First off, I quit! I am on day 11, so not 100% self-assured it will last, but I am 3 days smoke-free. I have no cravings to smoke, but the habit is still there, so if I am around triggers, I do tend to want to go for a smoke. I did try one today. I put it out. Made me sick feeling and tasted gross. Didn't even inhale fully. So it is working. Side effect: The nausea is INTENSE!!! Maybe if you eat properly, it will be less for you, I don't know. Sleep is horrid. I sleep at max 90 minutes at any given time. Most often I sleep in spurts of 30-60 minutes. As such, I am quite tired. I am on Topamax as well, so carbonated drinks like pop are off the table to help me with my day, so I feel drugged all day. Odd and rather vivid dreams. Not bad, just odd."

For Smoking Cessation "I successfully quit on day 6 and stayed for over a year and a half with Chantix. I did have a few side effects: nausea, had to take half doses after day 8, vivid but pleasant dreams, and constipation, but not sure if that was withdrawal or the Chantix. I recently started back smoking around the anniversary of my husband's passing and started Chantix again 3 days ago. I can already tell the want and desire to smoke is fading, and the taste is yuck. I would highly recommend Chantix to anyone that is SERIOUS about quitting."

For Smoking Cessation "I've been on these pills for two days. Today is day two. The side effects from these pills are horrible. They've made me nauseous, dizzy. I've lost all effort to do anything, all I want to do is lay on the couch. I didn't want to eat or even get up to go to the bathroom, I had to force myself. I just do NOT feel like myself. So I'm stopping the pills and finding a new way to quit."

For Smoking Cessation "I’m in my mid-50s and have smoked for 40 years. I began Chantix on October 28, and my last cigarette was on November 3. I’m in week 8 of the medication. I’ve always had nausea, especially with the evening dose, but taking it after I eat has helped. Some weird dreams, but not too disturbing. Lately, I’ve been experiencing some heart palpitations and almost a feeling of forgetting to breathe, then a gasp for air. I was thinking of stopping the Chantix, but not sure I’m ready yet. Oddly, what helps is that I carry 1 cigarette with me and know in my mind that if I end up smoking it, I’ll buy a full pack and be back where I was!"

For Smoking Cessation "I'm on day 20. And every day has been a struggle. I have noticed a decrease in smoking. From a pack to half a pack. But I'm so over being sick all the time. Even with food, I feel headaches and nausea. No weird dreams, but I am sleepy all the time. I would like to stay on it because the urge is going away, but I also want my life back. With my physically demanding job, I can't be sick all the time. I don't know what to do :("

For Smoking Cessation "I used Chantix for 4 weeks, and aside from the vivid dreams, it worked like it said it would. I had a lot of vivid dreams and light sleep. However, every time I smelled cigarettes, I would get sick to my stomach, and I still have that feeling today. It definitely made me quit after smoking for 23 years. If you are serious about quitting, this is definitely a good way to do it."

For Smoking Cessation "If it wasn't for Chantix, I may not have stopped smoking, as this was my last resort. In the past, I've quit, but only lasted several days, then I went back to it. I have now completed my 3rd week and have been smoke-free for the last two. Stopped smoking completely after day 5. Some of the side effects were/are slight nausea, joint pain in the hip area, strange dreams, a few 'nightmares,' but nothing worth stopping the program for, heartburn, and burping (I think has to do with the heartburn). I suggest drinking a lot of water and staying away from coffee (assuming you smoke with your morning coffee). I also started exercising regularly 4-5 days a week, an hour and a half a day. Thank you, Chantix. Good luck to you all, future non-smokers!!!"

For Smoking Cessation "My husband began Chantix 3 months ago. At first, he only had the physical symptoms of nausea, gas, shortness of breath, insomnia, and active dreaming. He was somewhat lethargic and hungry, eating all the time. However, by the end of the 3rd month, he was extremely irritable, unable to focus on any one task, very negative, somewhat irrational, angry, every day was a bad mood. I would NOT recommend Chantix. I don't really think the Chantix helped him quit. He quit on his own."

For Smoking Cessation "Maybe shouldn't have been writing a review at this point. 1st day taking Chantix, took 1st pill about 2 hours ago, no nausea experienced, positive reaction, I hope. Praying the rest of the journey is as positive as my first pill. Thanks for all the positive input from Chantix users, it made my mission to quit smoking even more certain. Will keep informed!!!"

For Smoking Cessation "Smoked all during my 20s, quit for 7 years, then smoked for 20 years but had tapered down to 1/2 pack a day or less. Had bronchitis twice last year, so got Chantix and started taking it around Nov. 1, planned my quit date for after Thanksgiving, and then just didn't think about it. Started forgetting to go out for a smoke during work, was down to maybe 3 a day by my quit date, ended up still having ONE a day in the morning for a few weeks, had 2-3 during my long Christmas weekend, and have had zero since. Side effects have been slight nausea even with food (but not every day), awesome dreams, somewhat lighter sleep, and a mild metallic taste in my mouth. Mild occasional cravings now, on week 10, nothing I can't ignore. Plan on tapering off soon."

For Smoking Cessation "I have been smoking for 30+ years and quit using Chantix. The only side effects for me were the nausea and wild dreams. Knowing the outcome was better than the side effects, I took it for 2 weeks, got through the hardest part, and moved forward smoke-free. If you get side effects and are determined to stop smoking, it will help!"

For Smoking Cessation "Champix is a miracle. I had been smoking a pack daily, plus another pack if I went out and drank that night. About a year ago, I decided I wanted to quit. I tried EVERYTHING: patches, gum, cold turkey. I even switched to snus for a while. I always went back to smoking. I thought I was never going to be free of tobacco in some form. My buddy told me his uncle used Chantix and it worked for him, so I decided to give it a try. My first week taking it was eye-opening. I had started cutting down without even thinking about it. No more car cigs, smoking less at the bar, smoking less in general. Then I switched up to the full dose, and the rest is history. I don’t crave cigarettes anymore. Drinking is really the only time I kinda crave one, but the craving goes away quickly. I swim every day and work out every day and am not held down by the chains of tobacco anymore. My only advice is to take Chantix a while after eating, or it’ll make you nauseous. Also, the dreams are wild, but you won’t have nightmares or anything like that."

For Smoking Cessation "I am on the 3rd week of taking Chantix. Stopped smoking completely after the 1st week and have not had any craving or urge to smoke. Nausea and dreams are manageable, BUT!!! I am constantly constipated, bloated, and gassy – these are very bad, embarrassing side effects, people. I will finish the 1st month with a lower dosage (1 pill a day) and will stop taking Chantix."

For Smoking Cessation "I am so grateful for this medication. I smoked a pack a day for over 20 years. The longest I went without a cigarette was 3 weeks. I tried the patch, the gum, and the electronic cigarette; nothing worked (though the patch was great for long flights). My experience is a little different than most because I never had bad dreams (they've actually been better) since I started, I'm never nauseated (though I make sure I take the morning pill after breakfast and the evening pill after dinner), and I didn't stop smoking until month two (not week two). On week two, the number of cigarettes I was smoking dropped down to about five per day. And I didn't even notice I was cutting down. I highly recommend this to quit."

For Smoking Cessation "Before, just the thought of trying to quit smoking stressed me more than it was worth, but for my family, I still wanted to try again. When I started taking Chantix, I told myself that I was not setting a quit date, that I would just see how it went. I only took the morning dose to try to prevent the possible sleeping problems. The cigarettes started tasting bad to me almost immediately, but I was too stubborn to let that stop me. After two weeks, I just started cutting back gradually, trying to break up my smoking routine a little. By the end of week three, I didn't need them anymore at all. I did experience nausea, but none at all if I ate before I took it. I'm smoke-free, and my kids are thrilled."

For Smoking Cessation "Day 9 of medication: Doctor told me all side effects and told me to hang with it for at least a week, hoping side effects would decrease if I experienced any. Day 9 and I'm just as nauseous as day 1. I eat a hefty breakfast every morning now, as I thought the first few days my breakfast just wasn't cutting it with the food intake, but still feel sick to my stomach instantly after taking it-I wouldn't say you will gain weight with this even if you eat more since after taking you don't want to eat for the rest of the day. By dinner time, I have to force myself to take the 2nd pill as I know for the rest of the evening I will be sleepy and uncomfortable. Some vivid dreams but nothing major. I feel the decrease of wanting to smoke, but sick all the time."

For Smoking Cessation "I am 26 years old. I have been smoking half a pack per day of menthol 100 cigarettes for 8 years. I am on day 14 smoke-free. After the 3rd day on Chantix, I couldn't even force myself to smoke a cigarette. Completely disgusted, even by the smell of second-hand smoke now! I only take half of the adult daily dose, and I still have zero urges. I have many vivid dreams at night, but nothing terrifying or crazy. My mood is very stable. The first few days, I felt a little agitated and felt some rage, but that could just be nicotine withdrawal. Now, I feel fine and I am a non-smoker. The only side effect that was bad was the nausea. I felt it the first week, very strong, but now I feel fine as long as I eat when I take Chantix. So thankful for this medication, it very well could have saved my life. I am just weary of the long-term effects of taking Chantix, which is why I will discontinue use after a full month and see how it goes."

For Smoking Cessation "I was nervous about this drug - scared I'd turn psychotic. I haven't yet! I'm in my 6th week, been a non-smoker for 4 of them. I take it after eating & with a big glass of water, that cuts down the nausea. Vivid dreams at first, no nightmares. I wake up in the night to pee, without fail, & that is only since the Chantix. I'm sleepy & kinda cranky...kinda very cranky sometimes!! But I can breathe & laugh without coughing. I don't start my day hacking my lungs up, it was going to kill me. I'm ready to start tapering, I'm going to 1/2 pill 2x a day for a week, then I'll drop to once a day, & then, hallelujah, my body will be my own again!"

For Smoking Cessation "I wasn't 100% ready to quit, but Chantix took over where my willpower could not. I only took the full dose for a week before cutting the pills in half. I had nausea (about 30 minutes even with a full meal and 8 oz. of water), gas/bloating, vivid dreams for the first 2 weeks. Week 3 has been interesting: I'm not able to go back to sleep after 1 a.m., I can't control my emotions (intense anger, then sobbing, then laughing). I was 'scary,' as my husband put it. The good news is I'm starting to wean myself off as of this morning and truly believe I'm over smoking. Good luck to all who take this-but make sure you have a great support group to ensure you are emotionally okay through the process."

For Smoking Cessation "I have been on Chantix for one week, and I have still been smoking the same amount that I was before taking this medication. I have smoked a pack to a pack and a half daily for the past 7 years straight. I have not experienced any of the side effects other than nausea, and the pills do not seem to be doing anything to me at all. It seems like I want to smoke more now that it is on my mind all the time."

The good: after the 8th day, I stopped smoking. I told myself I would quit April 15th, which I thought was just a dream."

For Smoking Cessation "I have been smoke-free for 3 months now and am a happy camper! Tried multiple times to quit smoking using several different methods, Chantix included. I have figured out that if you really are not ready or don't really want to quit, nothing will work. You can't be badgered into quitting, you need to quit because you are ready. I had some side effects: nausea, strange dreams in vivid colors, gas. It was all worth it! Took Chantix for almost 90 days. Still have urges to light up, but they pass after a few minutes. Started smoking when I was in high school, stopped when I was pregnant, then started right up again. I will be 60 next month. I feel if I can quit, anybody who puts their mind to it can."

For Smoking Cessation "Partner started taking Chantix and stopped a week later due to having breast cancer surgery. Was down from 2 packs per day to 1 pack per day - just nausea as a side effect. I started Chantix a week ago and have not completely stopped smoking yet. Down from 1 pack per day to 6-10 cigarettes per day. Side effects: gas, anxiety, nervousness, heart racing, sleeplessness, and a few vivid dreams. Didn't realize it could be from this medication. Will continue taking it so I can be there for her while she battles this cancer."

For Smoking Cessation "On Chantix, I've experienced constipation, gas, and nausea to the point of vomiting three or four times after taking a pill. Cravings were curbed, but I found that I (and everyone else I know who used it) cheated about once a week - buying a pack of cigarettes, smoking one, and throwing the rest in the garbage. I had to come home from work this morning because I kept vomiting. I'm giving up Chantix, and I'm going to try cold turkey instead. The side effects are simply not worth it to me."
