Did you ever address the psychological reasons behind why you did it before? I didn't, and here I am 13 years later, doing it again. I stopped before b/c my parents made me. Well, nobody's making me now. And u stopped b/c you were scared. Well, 2 years is a long time to get over being scared.
See what I mean? If you don't address the issues behind it, u will keep doing it. As my shrink said, the eating behavior is the symptom of the real problem, whatever that real problem may be.
Have you tried counseling?
