smoking cessation
"After smoking a pack a day for 20 years, Champix worked. I stayed at half the dose and after 2 weeks went down to 1/4 of the dose. Stayed on it for about 8 weeks in total. It was enough to keep me from smoking when I really wanted one. I did find there were side effects, but it was hard to tell if it was the Champix or not having nicotine in my system anymore.  I told a lot of people, family and coworkers, that I was taking it just in case so they could watch out for any serious side effects. Overall, I think it is worth a try."
