Personally, I'd start by getting a referral to a good dietitian who specializes in eating disorders. Your doctor should be able to refer you to someone.

You'll want an RD, by the way: Registered Dietitian.

Why do I say this? Because that's what it took for me. At first, I'd try to do it myself, and it was awful, so I would go back to eating that much less. Even with the RD it was very hard, especially since EVERYTHING was awful in my stomach. It took so long for my stomach to feel semi-normal again.

The worst is that it takes a while before your stomach will start emptying normally again. That means, you'll feel overstuffed for a long time after eating. There are two things t oremember when that happens: that it will go away, and that it's not really being overstuffed -- it's actually just not feeling hungry. THAT was the hardest part for me.

Also, everything's much, much easier if you are consistent and you work towards normal eating as fast as your RD suggests. Until you're eating more normally and consistently, your body is not going to readjust all that well. When I first started, I was retaining water in a weird way that my RD said was normal, but I felt like a blimp! Every ounce I gained seemed to go to my stomach and my boobs. Just where I couldn't stand it. But that goes away and your body readjusts. It's scary, but it will redistribute much faster if you are consistent with meeting your meal plan.

Best luck, and feel free to PM if that would help.
