been taking chantix for about 6 weeks now. finally stopped smoking a week ago although was down to a pack a week instead of a pack a day. I really only smoked those because I had them and I think I was smoking them just to get rid of them. Went to a wedding yesterday outside - people were smoking at my table and I didn't want one. I honestly feel like I've never smoked before except for one craving a day which lasts for a few minutes - before I know it - it's gone. I have been experiencing heart palpitations but it's HOURS after I have taken the pill - I had a pill at 8 am and it's now 2:30 and its like I'm having an anxiety attack. The dreams are vivid - bizarre - none scary though. nausea sometimes when taking the pill - I find that a LARGE glass of water helps.
