I needed rehab--not just detox--and I went to Hope by the Sea (often featured on that show "Intervention") for thirty days; it was amazing. Three years later, I went to the Renfrew Center for my eating disorder (because, even with AA, I had not totally surrendered)--and that was MUCH harder on ALL levels, since anorexia is my primary addiction. If you have the opporunity, take it. As other posters have said, it works if you are willing. With the ED, I wasn't necessarily willing, but I did it anyway--because there was a part of me that truly did want to get better.
I am crazy, insane busy with schoolwork right now, but I would absolutely make the time to talk to you, so PM me if you want.
