smoking cessation
"Am on 2nd week of Chantix, have not smoked in 3 days. Continued to smoke same as usual the first week of treatment. Still have slight cravings at certain times but it is manageable. No other side effects except as others noted crazy vivid dreams , but no nightmares. I'd recommend this way of quitting to anyone who are Leary or wonders if it works. It does block some of the pleasure you gain from smoking making it less enjoyable and easier to quit."
