smoking cessation
"I took chantix for 2 months, was very sick and very sleepy on it, but it worked. I have been smoke free for 13 weeks now, although I do still have strong cravings a few times a day. My biggest concern is that since going off of the chantix, I became very depressed, and started getting suicidal thoughts alot. Now I am on anti-depressants and anti-anxiety meds, which I had never needed before. My doctor thinks maybe I was borderline depressesd and that the chantix  pushed it over the edge."
