For Smoking Cessation "I'm in two minds about this drug. I'm on my third week and have not had a cigarette for a week now. I smoked around 20 per day and always found it hard to quit. Tried patches, inhalers, gum, etc., in the past but found the cravings really hard. This is actually working, and I'm not wanting a cigarette so much. HOWEVER, I feel awful. I'm extremely tired all the time and have zero energy, which isn't like me. I'm having terrible nightmares and other strange dreams and waking up in sweats. I feel sickly all the time with a metallic taste in my mouth, headaches, and over the last couple of days, I've had severe stomach cramps and terrible wind. Going to the doctor for advice. I do not feel good at all."

For Smoking Cessation "Second attempt at Champix, so far so good, but will say this time round I think I have every side effect: craving, feeling sick, strange dreams, tiredness, eating a lot more. I'm on week 4, but determined to do this. I smell better, my bank account looks healthier. Good luck to everyone."

For Smoking Cessation "I started Champix in November 2015. I have been smoking for 20 years! Stopped on day 14 and have had hardly any cravings at all. Side effects were intense to start but worth it: nauseous, tiredness, and the odd crazy dream. I am now on week 6 and thinking of lowering my dose. Can't believe how easy it was to stop with this medication! The only thing I am concerned about right now is my weight loss, I have lost over 1.5 stone since starting Champix. It may or may not be connected to the Champix."

For Smoking Cessation "I have been on Champix for 10 days now, my quit day was supposed to be on the 13th day, but thankfully I don't want a ciggy. I wasn't holding out a lot of hope for this drug to work, but so far, so good. Like a lot of others, I have had the funny dreams and lethargy, but not serious enough for me to stop taking them. Can't wait to finish the course and be normal again, but more importantly, I can't wait to be a non-smoker."

For Smoking Cessation "Champix works, but the side effects are pretty grim. After 4 weeks, I no longer smoke or drink alcohol. The nausea has decreased. The biggest problem is loss of weight. I have gone down from 103 lbs to 94 lbs, and my BMI now indicates that I am underweight. Has anyone any advice? Will this loss eventually stop? I am eating okay, and apart from feeling a little tired, am okay."

For Smoking Cessation "I would like to share my experience of Champix. I am now a mental health nurse who has smoked since I was 13. I want to strongly advise extreme caution against taking this medication. I had a constant taste of pennies in my mouth, I was tired all day and wide awake at night. I felt sick all the time, my vision was blurred, I felt moderate to severely depressed, having strange thoughts, significantly agitated, and hit a real low spot. My stomach was awful, I couldn't stop eating (I put on 2 stone in 3 months), and after 2 attempts on this drug, I didn't stop smoking. I stupidly didn't tell my GP, so I carried on, until one day I snapped, and my mum took me to the walk-in clinic, who told me it was this drug. It took around 3 months to feel myself again, and even though I am still smoking, I wouldn't try this again."

For Smoking Cessation "I am 52 and have smoked since I was 16. I gave up with patches 7 years ago for 3 years. Then started again. I have tried patches again and hypnosis, but nothing worked, so I tried Champix. A couple of people at work had tried and failed with it last year, but one lady I know tried it 4 years ago and is still not smoking. I have taken 14 tablets now and not smoked for 3 days, which is amazing for me! But the side effects have been (and have now stopped) horrible. I spent all weekend in bed under the quilt feeling sick, giddy, and spaced out. I have been constipated for two weeks (okay now), headaches. Tired. Can't drink wine or coffee! (Not really a bad thing!) But I am loving the dreams! It's working, so it's worth it!"

For Smoking Cessation "Now onto Week 5 of non-smoking with Champix. Have tried many cessation tools (patches, etc.), but this has been the best for controlling urges to smoke easier. However, side effects for me have been crazy, so will be stopping the course early. The side effects include insomnia, tiredness, lucid dreams, lethargy, swollen legs and ankles, sore feet, constipation, nausea, and mood swings that feel more in line with bipolar depression/quick to anger/anxiety/frustration. More than the usual nicotine withdrawal-associated symptoms."

For Smoking Cessation "If you wish to stop smoking, you will if you have the willpower. Using Champix, it may suit you, however, both my wife and I found the drug extremely disturbing. Following the starter pack, we both progressed to 2 x 1 mg tablets per day. During week 3, we were both like zombies. We were tired all the time and would fall asleep mid-afternoon. Nighttime sleep was disturbed by vivid dreams. Together with the almost constant feeling of nausea, it wasn’t for us. True, it removes the desire for nicotine, however, it doesn’t remove the habit. We both now use vaporizers and, having stopped the Champix, feel much, much better!"

For Smoking Cessation "I had a very negative experience on Champix. 5 days in and I've thrown away the packet. Day 1 I was nauseous and vomiting and had terrifying nightmares, dry mouth, hot sweats. Day 2 My mood changed, I felt like I was in a trance/had been sedated. Still having terrifying nightmares. Day 3, 4, 5 Sent home from work, feeling severely depressed and exhausted, can't function. I'm so upset that Champix affected me like this. I've read so many great reviews, but it just wasn't for me. I could have dealt with all the side effects if I didn't work full time. But even customers were picking up on my 'zombie' like state. Best of luck to everyone else trying to give up! I'm going to have to try good old-fashioned willpower!"

For Smoking Cessation "I started Champix mid-November 2015 and have been smoke-free for over 3 weeks now. I was a regular smoker for 40 years, and now this is the end of my smoking career. While the product works very well for me, I do find no energy, bloated, gassy, and no sleep at night. Also, my appetite has changed a lot, and my eating habits have improved as well, no sugars or fatty foods as cravings have dropped. A good way to lose weight. Dropped 6 kg in 1 month. Will now see how it will be once I stop the medication in mid-February. Best choice ever made."

For Smoking Cessation "Works well, but the nausea and tiredness are hard to cope with. Will this get less over time? Can anyone recommend ways to combat these side effects?"
