I remember looking at endless oral cancer pictures, reading all of the warning labels on every can, the surgeon general's warnings, and all of the annoying cancer hecklers that would chime in every time I popped a dip in my lip. None of that was enough to make me quit and stay quit. I'm sure we all know this or at least some before the first time we ever try it. We roll the dice anyway. One thing is certain, making bargains will not make the sores go away or reduce your chances of getting cancer.
I'm not trying to discourage you. Exactly the opposite. I hope you do quit and stay that way but I am finding that making the decision to quit for me was easier when it had nothing to do with reacting to possible consequences. For me it was in and of itself a personal choice not a personal threat.
