I found it easier to not crave one the first 3 weeks then after a few months. Once the 3rd month hits I start wanting it more. But at this point I am only smoking when I am drinking now. I don't seem to crave it any other time.
It all depends on you. You may never fight the craving like OBF. What are you doing to satisfy the craving?
I think it varies. I quit about 5 years ago....went 2 years. Then, had one with a beer and started again. I quit about a month ago. The biggest problem I have is that I had certain places on my drive to work that I always lit up....and that's when I think about them. I can tell you that after a few months, you relearn behaviors.
I caution you not to have "just one", or "one with a drink"....I felt confident I could only smoke when I drank, which isn't that often. Nope....my doctor says it's like giving a shot of scotch to an alcoholic....hard to stop at just one.
Hang in there....you will eventually start to feel better....
