smoking cessation
"I was a 2 pack a day smoker for 54 years.  I asked my doctor if I could try Chantix.  I did as instructed and continued to smoke for the first week.  At the end of the week, I stopped smoking and continued the pills.  After two more weeks, I was able to give up the pills too.  It has been a year now, and I have not had a craving to restart my smoking habit.  Thanks to Chantix, I believe I have kicked the habit for good."
