Yes, I have a food diary. It appears to me that dairy, all nuts, cinnamon, and pears are huge no nos that will make me sick for an entire day or longer. Fruits with a lot of acids (basically anything besides bananas, peaches, and sometimes cherries) are very likely to make me sick, and red meats tend to make me sick. Fish and chicken are usually ok. Fats and grease make me very sick as well but that is a gallbladder thing.
So I'm basically restricted to a select few vegetables, grains, eggs, and chicken.
I can't drink anything but water and occasionally some Gatorade as well.
