"Why hasn't the doctors found away to knock us out for a couple of weeks so we can wake up smoke free and no craving. "
Because it wouldn't work. In addition to being a physical addiction, smoking is a learned behavior. We have taught ourselve, over many years, when to light up to get the nicotine fix our addiction demands. Thus, there are two steps to becoming a successful ex-smoker:
a) breaking tthe nicotine addiction
b) teaching ourselves to fully enjoy NOT smoking in response to the triggers that used to make us smoke.
Here's a perfect example. You say, "But here comes stress and the need to smoke." That's actually a false belief that you have taught yourself. The only "stress" that smoking cures is the stress of nictone withdrawal 30 minutes after your last cigarette. Otherwise, smoking puts incredible stress on your body, starting with the massive amount of carbon monoxide poisoining in your bloodstream.
You've actually taught yourself to do something that kills you. Think how silly it is for us to believe that we get anything postiive from smoking a cigarette. Crazy, isn't it?
The cravings and urges are probably an essential part of quitting. But, rather than being some kind of horrible thing, they are part of a very positive learning experience. Embrace each crave, learn to respond by thinking about the wonderful benefits of not smoking, and then each crave becomes a learning experience that reinforces your effort to become a non-smoker. Each crave is a victory and each victory puts you closer to being an ex-smoker without craves. You are breaking a crave each time.
