Good point. It's five years for me - cold turkey. I did it by quitting for one day - every day. It seemed more manageble that way. Each morning I would get up and say to myself "one more day".
I can highly recommend www.whyquit.com and READ, READ, READ, all about what's going on inside your body. You'll find proof that cold turkey is the most successful way to stop smoking and WHY. The first month, I went to this site every day for support and studied all the educational material about tobacco addiction. It's a REAL eye opener!! It gave me the strength and wisdom to understand why I can never, ever, ever, ever take one puff. Because then you have to start this crap all over again.
You're already over the physical addition but you know have to go through all the stages of grieving because your best friend (that little white cancer stick) has died.
Rockpile has given you excellent advice in his posts.
Good luck - YOU CAN DO IT - YOU REALLY CAN. Just take it one day at a time and remember - www.whyquit.com
