smoking cessation
"I tried Chantix after smoking for 20 years, I did have horrible GI side effects, and vivid weird dreams. I was only able to tolerate for 3 weeks -- BUT, that was all it took to kick my 1 1/2 pack a day habit.  I never obsess about smoking like I did when I tried to quit with patches -- then I was following the guy who did smoke around after he went out for his smoke break.  I don't think about it, crave it, have any negative thoughts when I see someone ELSE smoking.  I love that."
