You could always replace one vice(in this case smoking) with a more harmless one, like picking your nose or spitting vigorously and often. Well less harmless to your health than to your social life anyway, cos smoking looks cool.

Seriously, I cant claim to know what going cold turkey is like mainly because I have never smoked before, but I know more than enough people that have tried and none of them have succeeded. And considering how bad everyone says the alternatives to straight out cold turkey are, it sound like one of the hardest things for a human to accomplish. So the best of luck with your endeavour.
