Your fears about being tempted to keep going are probably well founded, or at least that's been my experience. You already know that 500 calories per day is Not OK for your body, so I won't bother bringing that up to you, nor will I bother to tell you that those OTC pills are Not Good for you.

I'm hardly an expert on any of this, just someone who has battled weight and eating issues for almost 30 years now. My experience has told me that, in order to be safe from this, I have to gain enough to get out of my own personal danger zone. Getting into the bottom end of my "Ideal Weight Range" usually isn't enough, that's a danger zone for me because it's so danged easy to fall into wanting to lose just another five pounds.

I'm sorry you're experiencing this, and hope that you can -- somehow -- get your mind around it being OK to get to a normal, healthy weight and eat normally again. I'm not there right now, but I remember what it was like -- having spent almost a decade pretty much symptom free -- and it was *good*! I could actually eat something because I *wanted* to -- with no debate, no guilt, just wanting something and eating it. And it would taste so good, because it felt so free.

The best reason I can offer you for working on this honestly is just that it can keep coming up throughout your life, again and again, even when you think you've finally overcome it. That's been my problem, at least. It's not a case of seeking a cure, for me, so much as reaching remission and then managing it so that it stays in remission.

Best luck.
