smoking cessation
"Day 2 on chantix, my urge to smoke has decreased several fold. Smoke all of a sudden start to taste stale and unbearable. I also smoke marijuana so the taste of the green is still there !! 
Smoked since high school and now I'm 27 I'm half a pack a day kinda person. I did however experience a decrease in energy taking this pill, but however its only been 2 days. Will update in a week."
