remove yourself from civilization for at least 2 weeks--go on a horse pack trip, river rafting expedition, camping/backpacking, get someone to drop you off in a remote cabin--you get the idea. get yourself someplace where you CAN'T get cigarettes, and where you are removed from the social/behavioral context in which, typically, you would smoke or want to smoke. this sounds like the hell boot camp way to do it, and it is brutal, but it just might work. a good friend quit after spending 2 weeks hiking in the sierra backcountry. he was dropped at a remote trailhead, and after a day out, when he was jonesing really hard, it seemed like the better fate to be without smokes than to trek to the nearest store. he felt so good and was able to BREATHE so much better by the end that he was cured of the habit.
