I also can’t sleep when I am feeling hungry either. I need to get my stomach used to not being full so that it doesn’t stop me sleeping or functioning when I am awake. As long as I drink fluids there is no need to eat a lot. I will have lost pounds in just a week if I only have one meal a day. I feel sick due to hunger after only having breakfast and a meal in the evening. I don’t even like food any longer. That is not just because I want to lose weight. I don’t particularly like food any longer. I pick at stuff rather than eat it normally. I just don’t enjoy eating like I used to.
