"Chantix is a miracle drug. The best way for me personally to describe it is that it makes you feel as though you've just had a cigarette - all day long. Lighting a cigarette becomes a pointless and gross task as you're already feeling fulfilled and relaxed. I've been a smoker for 12 years and haven't felt so relaxed since before I began smoking. Stay on Chantix for at least 3 months, and don't ever go back to smoking/stressing out!"
