Any other heavy stoners else find that they were able to completely negate withdrawal symptoms and quit using tobacco with total ease, simply by setting aside a week and getting so blazed for the whole of it, that they barely even noticed the WDs?
That's what I did, and I seem to have had the most success quitting smoking of anyone I know who has tried. I also didn't ever decide to quit smoking, I just decided to see how long I could go without a cigarette, and after 20 hours thought, well, if I've made it this far...
I also found that a good coping mechanism was to say that I am still allowed cigars. Been well over a year now (maybe quite a bit over, I lose track) since I had a cigarette. I'd been smoking for about 8 or so years, very heavily. I think, twice in the time since I quit, I have been in that 'balls to it all, throw yourself away' place, but each time, I had a cigar. They sorted the immediate problem, but I think of them as different enough from cigarettes that they didn't re-trigger my fag habit.
Also, enjoy and really, really experience what your body tells you in the few days-1 week after quitting smoking. Fags smell goddamn disgusting, and as your sense of taste returns... well, I for one was kind of horrified to actually taste the food I was eating for the first time in such a long time. I think in that same week I lost a good potion of my desire for convenience foods, artificial sweeteners and flavorings, and food packaged in plastic that you wind up tasting right through to the core... bleugh. For me, quitting smoking also gave me a massive bonus crash-course in appreciating taste, and distinguishing food from, as Michael Pollan (Sp?) would say, 'edible food-like substances'
