"Here is a little story what made me try chantix..

I am a non emergency transport driver..I transport people with cancer yes lung cancer an they are either missing a leg foot arm or they end up with stomach cancer which is caused from smoking..so I decided that's it I'm not going to loose a leg or arm or anything like that because of cigarettes. .I'm not going to let cigarettes win a fight with me..I am so done..so I decided to try chantix. I have been on chantix for three weeks and have not put  a cigarette in my mouth since...it's a really great way to quit if you can't go cold turkey. I'm so happy who ever invented chantix."
