I still don't get how i fail. I not even a heavy smoker. I quit multiple times a year.
Early this year i quit from Jan 1st up til Feb 20th something. Then i smoke about one or 2 times a week if that. Then i quit again from May 15 til now, that's about 7 weeks. And i thought i would be fine. I didn't exercise or anything though, maybe that's why?
