smoking cessation
"I have stopped smoking as of 8/11/2011 while taking Chantix.  Before that date, I smoked a pack a day for 37 years.  Honestly, I enjoyed smoking and would not have quit until I was diagnosed with the beginning stage of emphysema (COPD).  At first, everything was going fine while taking Chantix.  It helped to ease my cravings, although I still wanted to smoke at times. When the cravings would creep up, I would just take my pill and the craving would greatly decrease.  During the two months of taking this medicine, I noticed that while it eased my cravings, I began to experience bouts of depression. I mean severe depression.  "
