To be honest, the gluten challenge under circumstances you describe (becoming violently ill- which is also what I experienced when reintroducing it) is not something I would care to do again, insurance or no insurance! I think you have your answer – just make sure you take a high quality gluten free multivitamin and if possible talk to a nutritionist who knows the pitfalls of the gf diet – or at least read about it. One of the problems I had (possibly as a result of the gf challenge i did) was I became even more sensitive to gluten – meaning whereas previously I could eat corn tortillas heated on a griddle where wheat tortillas had been cooked previously – after the gf challenge doing this would give me symptoms of having been glutened. Word of warning – for some of us, the reaction to small amounts of gluten gets stronger the longer we are off the gluten. In ways I regret doing the challenge at all, and there is no way I would ever do it again. So maybe you are lucky the challenge is not a possibility right now. Thanks for writing back. I hope all goes well for you and your family!
