Oh! I didn't realize you were still getting good nutrition. Your second post clarified, thank you. Do you feel like you know what healthy calories and portions for you are? Is it just a question of helping yourself stick to them? Do you know what is triggering binges? Do you start out hungry for a healthy meal, but then have a hard time getting stopped once you've had all you needed? Do you like "getting away with something" when you binge undetected when no one is around? Do you feel "hungry" or empty in some other way?
Those would be some of the questions I would ask myself to try to get binge eating under control. I am also wondering, since it sounds like you are eating healthy things, if you are truly binging, or if it just feels that way compared to undersized meals that you may have become accustomed to while restricting your eating?
I am glad your boyfriend is a good support. If you made a meal and snack plan for times when he's gone or asleep together, would that help you stick to it?
I feel I asked you more questions than I answered! I'm sorry! I commend you for all the great work you've done so far learning about nutrition. I have faith in you that you will continue to improve in these obstacles.
