The cravings DO go away. I quit cold turkey 23 years ago after 23 years of daily smoking. Up to 4 packs a day at the end. At first I wanted a cigarette constantly. It's true that every time you don't give in to a desire to smoke you diminish the power of what triggered the desire and eventually it stops being a trigger. About a year after I quit, I suddenly realized that I hadn't wanted a cigarette at all that day and in fact couldn't remember the last time I had even thought about it. It was the hardest and most worthwhile thing I ever did for myself. If Smoker's Anonymous still exists in a neighborhood near you, I highly recommend them. I doubt I could have done it without all their tips and support. Good luck everyone.
