The gluten challenge is not going to well. Frankly, I'm quite ill. I have horrific heartburn, chest pain, reflux, salivia production, searing stomach pains, nausea, chills and sweats. I'm done doing this. Today I ate a regular toast, a tortilla, soy sauce, part of a cookie, some dry wheat cereal and homemade chicken noodle soup. Who gets heartburn from chicken noodle soup??? I'm ill. It's just not worth it.
