smoking cessation
"My husband and I celebrated one year smoke free on March 5, 2010.  Both of us were 30-year smokers, I smoked 2-3 packs a day and he smoked 1-2.  Chantix was the magic pill we'd always joked about!  The only side effect we suffered was constipation (we know two other people who had the same easy experience, but two of my cousins had to stop because of vivid nightmares).  I feel very lucky that Chantix worked so well for us.  Neither of us has had any interest in smoking since we quit."
