Some addicts say giving up cigs is more difficult than giving up heroin. I was able to quit smoking by first using nicotine gum for about 2 days, then I replaced cigs with joints when I really needed to smoke something. You'll be a stoner for a while but it helps your need to hold a 'cigarette' and do something with your hands. Also coffee (with caffeine) would help take the edge off nicotine cravings. Keep telling yourself "I don't smoke". Think of the $ you will save. And don't worry about weight gain, that's temporary. You can do it!
