I am in that phase right now. It is terrible. I know the pain you are going through. You are so hungry but when you get the food out to make it, the smell makes you want to v*. I have lost 7 pounds already from not eating and it isn't getting any better. I just ate a banana and some applesauce for lunch to make my stomach stop hurting from hunger pains. I know we can get through this though.
What I have been trying is taking small bites in a long time frame. (of course under the 2 hour contaminated food time limit) Just see how you do after that first bite. Usually it makes me feel better and I can eat at least half of my meal. Keep holding on, you can do this!
