I've been really trying to pay attention to getting nutrients into what I'm eating, so instead of taking a vitamin or something like that I'm getting what I need for my body from my food intake. I added some unsalted peanuts to my smoothie and it seems to have really gotten rid of a little hungry feeling i was getting that was making me crave some chips or something.
Try to see the positives, you're maintaining, and take some little steps to try and maybe put together 2 good days to 1 bad or a day and a half, but definitely try and look at what you're eating on your binge days in terms of what you might be lacking, if you can change your mindset to look at what's happening in a scientific or troubleshooting kind of way, trying to see if you're looking for fatty, salty, carby maybe some kind of trend, it can help you figure out what you need to add in on your good day to help you get in control.
Also, if there's an emotional component, since you're saying every other day, it might be easy to overlook if it's because every other day you have some stressor...hope things get better for you, I'm sure you can adapt and overcome.
The first step is admitting you're powerless, then you start working on how to deal with that.
best to all
