Are you sure that's healthy? Doesn't that just trip starvation mode in your brain? Maybe you should just stick to like... some very simple healthy foods for a day or two? I can't afford not to eat at all without screwing up my blood sugar levels and risking a seizure. When I came off my binge I limited myself to bread and cheese with water and fruit-infused tea to drink for a couple of days before I was able to expand to actual fruit and beans. (Oh my god, I craved chocolate so hard for the first couple of days, and I still do a bit right now.)
You should eat some lighter fair until your body stabilizes rather than cut yourself off. You really do risk messing up your blood sugar if you jerk yourself around too much on your nutrition, and I've always found not at all eating anything just makes cravings worse. Try and take the edge off with like a plain bread and meat sandwich. Maybe make a couple and cut them in half and eat a half every couple of hours with a snack in between and see if that doesn't take the edge off your cravings. By eating more often, you might be able to convince yourself you don't need to eat as much. It'll still be hard, but I find it helps me when I'm not in the throes of an active meltdown.
