If you could do anything, what would you do?

OK, here's the question. Supposed someone came to you and said he could guarantee you would never again have to battle weight (or whatever your bad habit is). You would be "cured" of all cravings. You would never want to go off your program. However, the price would be that for the rest of you life, you had to follow a very specific, unyielding, exact program and could not waver, no matter what the circumstances. If you made one slip, you were off the program and regained all your weight and could not start again, would you give up all choice to achieve that?
