OA anybody?

Hello everyone- hope everyone is doing great.  i've been on my new healthy living plan now for just 5 days and am doing and feeling great.  I have a fear though that I will soon get that compulsion to cheat and it really becomes overwhelming.  Has anybody ever tried overeaters anonomous before?  I thought it might help when i get that strong urge to eat what i know I shouldn't.  Let me know-thanks
