I've heard really great things about Chantix, as long as you stick with it. Good luck with quitting. My grandfather smoked since he was 17 years old, he quit about 6 years ago after a major heart attack, and he just died of stage 4 lung cancer that they could not catch quick enough. It was VERY hard to watch him die like that, no one deserves it. Unfortunately, we are ALL going to die sometime.
