Congratulations!
I quit cold turkey 3 times in 30 years of smoking, every time after 2 years a switch went off and I was smoking again. Even after quitting I still wanted a cigarette most of the time. This last time has been different though, I went to a hypnosis class at a local high school and haven't had a smoke or even an urge to have one ever since. Going down the parkway behind a car with a smoker, I can smell it if the windows are open, my sense of smell and taste are much better.
The cost for the class was $42, and an extra $15 for a CD or cassette. A woman in my office went to a hypnosis session at a local Holiday Inn, her and her husband paid $500 total, it seems they get people so worked up that they buy all the supplements and such, as always buyer beware.
Good Luck, you're a non smoker now!
