Whatever accountability system I put in place, I would be able to "crack" it if need be. I think maybe I feel that a hurdle I need to jump is to WANT to stop on my own, not because I have to but because I WANT to.?????
That's an altruistic reason.
It's also playing with fire, IMHO.
There's also something to be said for putting the BEST tarnsparency/accountability system in place that you reasonably can. Would it be foolproof? No. But just as the credit cards frozen in a block of ice in your freezer makes them tougher to use, so would a good plan help you maintain your no-contact pledge.
