Hi everyone, I started taking champix and I am on day 14 now. Before I started taking them I was nervous, because my brother had used it in the past and his symptoms was horrible. So he quit champix and is still smoking today. When I took the first pill I had like this instant dislike for the taste of cigarettes and that was fantastic. I have had almost no side effects and I am very positive. The last few days when I take the morning pill I have like 10 minutes of nausea but than its over. But today, on day 14 I am very tired, I am struggling to keep my eyes open at work. I had a good rest and no weird dreams. I am just wondering if anyone else used champix and everything was going well and than later started getting side effects. Because so far I thought I was one of the lucky ones that would get the minimum side effects, so just want to know if I should prepare for the worst. Just want to add that I have been smoke free for a week and after 16 years of smoking that is a fantastic feeling!!
