Just found this place and thought i'd register to keep me focused on quitting.
I'm on day 14 of Champix and been smoke free for 6 days now. Barely have any cravings but I do think about cigs occasionally but never really tempted.
The only real side effects I've had from Champix so far are nausea after the first one of the day, and on the occasions I've gone out drinking my tolerance seems to have vanished meaning I was plastered!
Slightly concerned about the weight gain side effect as I keep myself fit but so far I've actually lost weight and I haven't noticed any change in my eating habits - if anything I eat healthier now.
Keep the faith.
