smoking cessation
"3 1/2 years ago I decided to take Chantix to quit smoking.  For me Chantix was a miracle.  I have had no desire to smoke since I quit.  I feel so much better and breath much better.  I smoked a pack per day for over 20 years.  I was feeling short of breath and exhausted all of the time.  Not any more.  Thank you Chantix."
