smoking cessation
"Been on Chantix for 2 weeks now, get the nausea (but just now read to take with food) and vivid, fun dreams.  Other then that no other adverse side effects.  Been a smoker since I was 13 years old, now 46 and average pack-pack 1/2 day.  With Chantix down to about 1/2 pack per day.  But not a strong urge to quit, hopefully soon. "
