I've gone from one set of disordered behaviors to another, but when I was the sickest, I was in a binge/fast cycle. I'd starve myself to the point that my hunger would make me lose control, I'd binge, and then the guilt and fear of weight gain would lead me to starve myself again.

I had to go to therapy to break out of the cycle, and I was put on a meal plan where I had to eat a controlled amount each meal to avoid starving or over-eating (Exchange System). It worked really well for the short time I was on it.
