I went to a OA meeting once a few months back.
I'm not sure if I just wasn't ready or what but I didn't go back.
It works on the same principles as AA, but the thing that got me was that even the skinny people who had seemingly overcome their issues were still saying, "hi my name is .............. and I'm a compulsive overeater." That made me feel like I would never be rid of the title and I just couldn't go back.
A lot of the stories people told were easy to relate to, but it's a strange way to deal with it I think.
I'm still a skeptic, but good luck, I hope it suits you.
Winners MAKE things happen,
Losers LET things happen.
