"It's been 5 years since Chantix killed my multiple decade, hard core, 2.5 pack a day, tobacco smoking addiction. Given the very vocal community against the medicine. I think it's important that those of us who's lives have been saved by it speak up also. Chantix gave me some weird but not unpleasant dreams and made me moody. However, cold turkey withdrawal, makes those side effects seem laughable as cold turkey attempts would make me close to completely irrational.  Chantix is a miracle, don't miss out on it.

As a final note, I do have to say, while Chantix does the heavy lifting, you still have to be committed to quitting. TO THIS DAY, when I see someone smoke, I still have pangs of longing, however I also have a healthy terror of smoking."
