On January 3, 2007, I will have gone 1 year without a smoke after having smoked for just over 20 years. I went cold turkey with minimal weight gain. I rarely ever have a craving. When I do, it only lasts for a few minutes.
I was one grumpy SOB for the first month or so (my wife will argue thatI'm grumpy all the time, but I think that's just due to age).
For those attempting to quit, if you set your mind to it, and
really want to quit, you can do it. Good luck!
