I am having so much trouble with the pre-op diet, I was originally scheduled for 01/17/13 and they rescheduled me to 01/22/13 because the Doctor was overbooked. I am only allowed the protein drinks, cottage cheese, yogurt and then veggies and fruit. But by 5 pm I am so hungry. I have cheated, tonight I ate some vegetable soup, but I am staying within the calories that I am supposed to. Not sure if it is the calories they are wanting or if it is the types of food that we are allowed to eat.
