i have been gluten free for almost a year now, and with excellent results.
i also had to take three courses of xifaxan for bacterial overgrowth. i keep a regemin of gluten free, acidophillus and enteric coated peppermint oil pills. (the peppermint oil is supposed to be similar to what cranberry juice is to urinary tract infections. it can cause some people diarrhea, i fortunately, am not one of them. it helps the small intestine...which is where my bacterial overgrowth was.)
gluten free is very difficult, and expensive, but for me it is easier then feeling sick every day. i also think gluten free is a healthier diet, i mean i cannot eat most of the processed foods found in the grocery store, and no fast food.
being gluten free is getting a bit easier now that the FDA has gotten involved, packaged products now have to list all the allergens under the ingredients.
i am sorry i have no magic suggestions, but for me gluten free is the way to go.
best of luck to you!
what would you attempt to do if you knew you could not fail?
