Heh, nice idea. But doesn't apply to me because I don't smoke.
This seems... silly. I have serious doubts as to the effectiveness of this method - if you're having serious cravings, no arbitrary action like a dice roll is going to help you resist it. It's a nice idea, and more power to you if it actually works, but I just don't really see how it could work that well.
I still think the best way to quit is to stop putting cigarettes in your mouth and lighting them.
This is awesome. Although, I couldn't help thinking when I read this that it's a reason to start smoking... Still, the reasons not to far outweigh that.
