"I smoked for 14 years, tried quitting several times but always went back to cigarettes.  At first, I was skeptical about taking champix, the side affects alone are enough to scare anyone off.  I researched and researched, read all the positive and negative reviews and thought to myself, the positives definitely out weigh the negatives, I mean anything is better than smoking.  I took champix for 60 days and quit about two weeks.  I had minor side affects, such as: nausea, sleep disorder and felt spaced out most of the time, all well worth the final outcome...smoke free.  I am now smoke free for three months and I couldn't be happier.  For those of you thinking to try to it, I would definitely recommend the medication. Stay Strong!"
