I agree ! I had IBS for years (couple of decades) before getting sick with a bad virus that wouldn't let me keep anything in for a week. After that I could not tolerate gluten at all (took a while to figure out). Anyway, 5 months after being gluten-free my doc tested me for celiac and of course it was negative....but I am very sensitive to gluten.
I have 'fixed my IBS' but eliminating gluten completely - and avoiding dairy 99% of the time and soy as well.
