Smoked for the vast majority of 40 years, took CHAMPIX for one month last August and havent had a smoke since, and I found it EASY surprised the hell out of me, still get a craving now and then but they dont last long, BUT i reckon if I had one i would be back on them full time, I actually enjoyed smoking but knew that it was time, have a new Grand Daughter and want to see her grow up, and want to live long enough to be a burden on society lol
