You just giving up Tobacco or giving up smoking altogether? My friend Tom's advice for giving up cigarettes is to become addicted to Cannabis instead. It works because cannabis is more trouble to get hold of than Tobacco, so it often isn't worth the trouble to get rid of the cravings...
Still, I'm not sure how much pot you'd have to smoke to get addicted. Must be pretty much - I've never known anyone to get addicted...
I'm blethering. I'll shut up.
