The best you can do to deal with stress eating is to plan for such a contingency. Make sure your fridge and pantry are stocked with complex carb snacks, and make food that is too caloric dense less available. Your lizard brain will be less likely to want to binge if food isn't as easily accessible. Complement snacks with protein so you get satisfied faster, stuff like eating a piece of chocolate with a pint of greek yogurt and a bunch of splenda REALLY REALLY hits the spot without putting on a lot of calories, there are probably a bunch of low-cal high-protein recipes online which you can try for emergency cravings. I have to disagree a little bit with calorie counting, only do this if you're really unsure as to where the extra calories are coming from and until you get a feel for caloric contents on food, but in my case it just made my ED worse in the long run, so I'd be cautious if you think you have an ED already. And yeah sleep well, not sleeping well makes you waaay hungrier, but you already know this. The most important thing is to not beat yourself up if you end up binging, it happens. There's really no hurry and you should take your time.
