You can't eat at night. Even if you can't help eating, don't go to bed at once. At least you should do some small exercise and stretching. It is easy to get edema when sleeping after drinking water at night, and try to urinate before going to bed. If you eat too much at one time, you can induce vomiting, but you can't use this method often.
If you really want to eat, you will feel full if you prepare diet food such as raw lettuce at home.
The key to losing weight is persistence, and persistence is victory.
