Different things work for different people. Some people can quit cold turkey.
I couldn't have said it better myself. My father smoked for over 50 years. Then, about three years ago, his ticker started giving him some trouble and he had to stop on the way up the stairs one night. He looked at my mother and said, "I'm done. No more cigarettes." And he hasn't touched them since.

Me, when I quit smoking cigarettes, it was pretty much cold turkey, along with my wife. I sneaked a few here and there, mostly because friends were smoking and I did miss it. But I'm at the point now where, even if I'm around friends and I get nostalgic, I remember just how bad the last one tasted and I'm "cured" for the moment.

Nicotine is a tough drug to beat, especially in the short term, but the war inside your mind is a worse fight. My addiction was far more psychological/social than physical (although I did have some physical withdrawal).

Good luck to you. If you really want to quit, you can.
