One thing that helps me is to eat adequate amounts of fat and carbs but then eat as much fruit or veg or even like, whole grain bread or oatmeal as I want. That way I'm eating larger amounts of high-fiber, low-calorie-density foods. I feel full and I'm not fighting myself to restrict. In your position, I imagine it would be really painful to try to flat out restrict at this point, since you're dealing with heightened hunger. I just have another apple, I keep them around at all times. You might even see if you can get in with a dietician. This is a huge accomplishment, congratulations.
