For Smoking Cessation "ddferrari, I don't believe these people are faking about their experiences. Because I had a good experience with Chantix. Honestly, I am smoking again. I took this a couple of years ago for about a week or two and went from a pack a day to a cigarette every three days. So it did help. But it did make me super tired, so much to the point I felt sick constantly. I was having dreams. Dreams about my boyfriend cheating on me (which he was). I'm about to start taking them again. I had stopped back then because of all of that stuff. But I'm going to start again because I did see an improvement. This time I really plan on stopping..."

For Smoking Cessation "First of all, Chantix is great! The side effects I'm feeling are being extremely tired. I even fell asleep at work. I have not been able to get up and do my workout, instead, I fall back to sleep in my chair. I also am experiencing the weird dreams. I wake up not knowing if some things are real or if I dreamt them. The last few days felt very blue too. The positive is I haven't had a cigarette in 9 days!"

For Smoking Cessation "Amazing. Yes, of course there were side effects. I felt tired and a bit nauseous about an hour after taking the pill. I countered this by taking the 'evening' pill at night before bed, and then I would be fine. I had a few vivid dreams, but nothing crazy. This medicine works...if you really want to quit smoking. It isn't magic, and you do have to put some effort in. Of course, you will be cranky and a bit more anxious than normal, your brain has no idea how to deal with stress without smoking. None of these are reasons to not try it. I was a pack-a-day smoker for 15 years, and I have not smoked for 10 weeks and have zero desire to do so. It's truly a miracle medicine."

For Smoking Cessation "I started taking Chantix after smoking for 15 years. I am halfway into week two. I have quit smoking completely, however, the side effects are awful. Headaches, tiredness, irritability, crazy dreams that seem real, sensations throughout my whole body, dry mouth, dizziness, constant feeling of hunger."

For Smoking Cessation "I started Chantix two weeks ago. My doctor started me on a half pill once a day. After 4 days a half twice a day. Then a full pill (1 mg) twice a day. I have minimal cravings. I do give in at night and smoke a couple of cigs in front of the TV. I think if I change my late-night habit of TV for a while, I can break the cycle. Chantix is a miracle for those who can take it. The only side effect for me is lethargy. It's worth it, and I'm saving money besides my life!"

For Smoking Cessation "It works if you let it! I'm very pleased, it's only been a month, but I can DEFINITELY see/feel the difference. I've had moments when I would get a just 'little' cranky, but nothing I can't handle. I've experienced those dreaded dreams, but I haven't experienced the 'waking up in a cold sweat' kind of dream. They're mild, nothing too crazy, thank God, lol. But the worst thing for me is the nausea and the tired feeling. With the nausea, I had to make sure I had something on my stomach and still keep ginger ale at my side. The tired feeling got so bad I started taking them at night because I wasn't able to really perform at work. Everyone is different, but I hope some of this info helps. GL!!"

For Smoking Cessation "I used Chantix to quit 4 years ago. Don't remember having any side effects then. I went 3 weeks without a cigarette and was feeling really confident, so rather than spend the money on a refill, I decided to try it on my own. Huge mistake! Within 2 weeks, I was smoking again. 4 years later, and I'm ready to try again. I'm on week 3, and it's not working quite as well this time. I'm still smoking, but considerably less than before. I'm down to about 3/4 of a pack a day compared to my usual 2 or more packs a day. I'm definitely having more side effects. So tired this week, I could barely function, and upset stomach all day, but it's getting better. I plan on taking the recommended 3 months this time to increase my chance of quitting for good."

For Smoking Cessation "I started my Chantix on Tuesday, which would lead me to only being on this medication for about 3 days. I am usually smoking about a pack/day. Since I started Chantix, I smoke about five cigarettes a day, and I'm only on day 3! My doctor told me that I would most likely continue to smoke for about two weeks while taking this medication. I'm already feeling the difference. The only side effects I've been dealing with are tiredness, nausea from taking it on an empty stomach, and some agitation."

For Smoking Cessation "I was on regular dosage Chantix for about 3 weeks and stopped because of persistent nausea. I quit smoking after the first week and have been smoke-free since (total of 60 days now). I am still having bouts with nausea and feel lethargic and borderline depressed at times. Also have some bouts with disorientation-like sensations during times of nausea. It's great to me off the smokes, but I could do without the side effects."

For Smoking Cessation "I have been a smoker since I was 14. I am now 28. I tried Chantix for the first time about a year ago. It worked wonders. I was smoke-free for 6 months. I had no problems with it at all. After the 6 months, my boyfriend, who at the time did not quit, was smoking, and I would sneak a few drags here and there, and then before I knew it, I was back to smoking. I started Chantix again 9 days ago. I have been nauseous every time I take it, very tired, and VERY VERY moody to the point my kids do not want to be around me. As of today, I will not be taking Chantix and will turn to another alternative. Good luck to those who do have success with it!"

For Smoking Cessation "I have been on Chantix for 8 weeks. I have smoked for 42 years and smoked 1 1/2 to 2 packs a day. Now I have one cigarette about once a day or none. I just started getting nausea, I am tired all the time and feel a little down. But if I can quit, I would think this will go away once I am off the pills."

For Smoking Cessation "I am 45 and have been smoking for 30 years, at least a pack/day for the last 20. Started taking Chantix July 1, stayed very loose about it and had my last cig sometime between July 6 - 8 (don't remember). I guess because I already didn't really want that last one - it was just there. Today is Oct 10, it has been about 13 weeks, feel good about it. Some vivid (weird) dreams; some nausea (that I didn't pay much attention to until I read these comments). A little lethargy... all in all - IT'S GREAT!"

For Smoking Cessation "I started taking Chantix the last week of September, and I have been smoke-free for three weeks! My doctor only gave me the prescription for a month's worth, so now I am off of it. Today is the second day without taking Chantix, and my mood has been changing. I am yelling at everything, and I am so tired. I even realized at the last minute that I was allergic to the stuff. I am glad that I am smoke-free, but I will be glad when the medicine is out of my system."

For Smoking Cessation "I'm just entering my 3rd week of using Chantix. It has definitely decreased the craving for cigarettes. However, I find myself having to continue to smoke. I don't smoke as much or even smoke much of the cigarette. I do experience great vivid dreams, not nightmares, the nausea, which I have found that wintergreen Life Savers seem to help settle my stomach, and I'm tired a lot, but until reading these other experiences, didn't know it was connected. I am currently taking antidepressant medicines, and my doctor watches my behavior every day, since I work in the clinic, and I'm very aware of my moods. I get irritable at times, but so far no real depression, so hopefully the Celexa I'm on is helping that. I would recommend it to anyone!"

For Smoking Cessation "Started taking Chantix after smoking for 22 years... 38 now, and I have been on it for approximately 1 month. Drastically cut down on smoking during the first 7 days and have not had a cigarette or even a drag for the last 2+ weeks. The side effects that I have had are headaches over the left eye (almost like the onset of a migraine), a slight bit of nausea, which was cured from eating a decent meal before I ate, a little tired, extreme irritability, and weird dreams. No more smoking though."

For Smoking Cessation "I am on my third week, and I have cut down to approx. 3 to 4 cigs a day. I noticed that I feel tired a lot and feel nausea only when I smoke and a slight headache, but it doesn't last long at all. I've had one nightmare and have had loss of appetite and weight loss. Also, I notice that it intensifies the effects of alcohol."

For Smoking Cessation "Day 2, definitely noticing reduced cravings, but super nauseous and weird pain in the left side of the neck, plus super tired even though I've been drinking a lot of coffee. I've been reading the reviews online, and I'm not willing to continue taking it with the serious side effects I'm reading about."

For Smoking Cessation "My boyfriend and I are on day 7. I have the metallic taste in my mouth and am tired. Chantix has curbed my urge to smoke, and surprisingly I don't even want a beer anymore, which of course is GREAT. I went from smoking a pack a day to having only 1 to 3 cigarettes a day. I can go outside with my co-workers while they smoke, and it doesn't bother me. My boyfriend's symptoms as of today: he is very tired, has developed feelings of anxiety, gags, and feels nauseated when he attempts to smoke a cigarette. He had a check-up at the doctor's today, and his heartbeat went from 72 (last week) to 53 today. They did an ECG on him and told him to go home and rest for a couple of days."

For Smoking Cessation "During the first week of taking Chantix, I smoked. I did not notice any decrease in my desire to smoke but noticed a significant increase in my tiredness. The beginning of the second week of Chantix, I quit smoking altogether. The tiredness was still there, and after taking the pill, I would have nausea for a short time. It didn't matter if I had just eaten or not. I also became moody, depressed, short-tempered, and just generally felt down. I stopped taking the pill today, which has been 2 1/2 weeks on the pill. I'm hoping for no worsening of my mood and energy level."

For Smoking Cessation "It's been a couple of weeks on Chantix, and I finished my pack of cigs for two days, then cut back to 3 a day for 3 days. Now I haven't had any for five days, and I feel like I never smoked. I don't even think about it. I wanted to write in here to let everyone curious about starting Chantix to ignore the horror stories and try it for yourself. I have tried the patch and lasted nine months, and having a cig was all I thought about the whole time, it was awful. Chantix has no nicotine, and it's been wonderful. As it states on the box, please take it with a meal, as it does make you very nauseous if you don't. The only other side effect I had was it made me extremely tired the first two or three days."

For Smoking Cessation "I just began Chantix and really want to quit; after one day of taking the medicine, I have a severe allergic reaction, rash in the buttocks region. I have also felt sickly, lethargic, and have strange visions. I have several friends who have taken the product with no side effects whatsoever, so I believe it is a case-by-case basis. Immediately, it curbed my cravings, and cigarettes tasted horrible. However, I must be too sensitive to the drug, so I will look to going cold turkey or reduce the dosage."

For Smoking Cessation "Today is my 6th day on Chantix. I've been smoking for 13 years. I'm 25 years old. I've noticed a small cut down in my normal pack a day, and I am more likely to have a cig than smoke the whole thing. Everything tastes different, and I am very tired. No vivid dreams, surprisingly, but I have a lot of trouble falling asleep. I really need this to work. I have been using my inhaler a lot the last month or so, crossing my fingers it works for me."

For Smoking Cessation "I am a pack-a-day smoker for about 10 years now. I am really ready to become a non-smoker and say I overcame the addiction. Today is my 8th day, I have been feeling sick the last 2 days and having some 'off-the-wall' dreams, but funny dreams. I am tired during the day, but when I am at home, I am good. I work and go to school, so my only concern is that I will not have enough energy for both. So far today, I have only had one cigarette, and I only took 2 puffs and threw it out. Praying that this works as I start my new life as a non-smoker! Good luck to everyone out there who has just started!"

"I have been a smoker for 35 years, tried cold turkey, patch, classes, nothing worked. Chantix is amazing. Yes, I feel tired, trouble sleeping, but do not have the slightest taste for a cigarette. Now the amazing part: 35 years heavy drinker, have not had a drink in 1 month. Just lost my taste for alcohol. THANKS, CHANTIX."
