Ive always thought that addiction is mental as well as physical. Your body becomes physically dependent upon something and your mind craves it. Once you stop, you get withdrawal which is a shock to your body that the steady stream of whatever it is has stopped.

I quit smoking about six years ago when they outlawed smoking in bars here in MD. Im not much into the bar scene anymore but back then I remembered thinking that I was not about to go stand outside in the freezing cold just to smoke a cigarette and then have to go back and do it again in another half hour. I was able to back myself down slowly and then with the help of patches (and anti-anxiety meds) I was able to quit completely.

You might want to go and have a talk with your Primary care doctor. He/she can give you ideas and I have also heard a lot of people say good things about chantix as well. Its worth a shot and I am sure they have had patients come to them before wanting to quit smoking. If you want to quit now, the sooner is the better!! My father is a life long smoker (30+ years) and once you get that far in, there is almost no stopping.
