smoking cessation
"I used Chantix to quit 4 years ago.  Don't remember having any side effects then.  I went 3 weeks without a cigarette and was feeling really confident, so rather than spend the money on a refill, I decided to try it on my own.  Huge mistake!  Within 2 weeks I was smoking again.  4 years later and I'm ready to try again.  I'm on week 3 and it's not working quite as well this time.  I'm still smoking, but considerably less before.  I'm down to about 3/4 of a pack a day compared to my usual 2 or more packs a day.  I'm definitely having more side effects. So tired this week I could barely function and upset stomach all day, but it's getting better.  I plan on taking the recommended 3 months this time to increase my chance of quitting for good."
