Everyone with GP tolerates different things. I've tried spinach twice and I throw it up immediately. Small amounts of squash and mushrooms are ok. Any kind of meat, chicken or fish makes me sick. It's hard for me to eat very much food. Often a 1/2 cup total of food will leave me feeling like I had a 5-course meal and the fullness and nausea don't go away the entire day. Some days I can eat more. I really need to find a liquid diet that is IBS safe, I'll be patient for the next two weeks, but I don't know that I can handle all this solid food. I've had 600 calories today and I feel stuffed, bloated really bad and nauseaous.
