I don't remember if I have asked you this before but have you had anything suggest you may be gluten sensitive? Like blood or stool antibodies or abnormal gastroscopic biopsy?
Just asking because I just had another blood test for gluten antibodies. My doctor said that they used to test for another antibody and that this test was only accurate in children and that they now test another type of antibody in adults. Anyway, the test came back negative. But when I mentioned to her today that I know of people who didn't have any blood antibodies but still responded really well to a GF diet she offered to refer me for a gastroscopy. This is the only test I haven't had so I think it's good. Plus I didn't even have to ask for it. But that's not all - she actually said she'd refer me to a private practitioner and she said she thought that we'd get it done and maybe even get the results before Xmas! Total shock. But in a good way of course. Now I hope something will show up so that I get a really good reason for trying a GF diet. It's easier to decide to give it a real shot if you really suspect it. And it would be so much easier to be gluten sensitive than having IBS. I still have problems from time to time and tend to do the BTC diet like once every one-two months parts of the year. And I am still on loperamide daily. I have had problems with blood sugar fluctuations and just now tried eating root veggies and bread with my main meals instead of bread and rice/potatoes and a smaller amount of veggies to see if that would help. But I can tell you this - my bowels were not very happy with that decision. So please wish me luck with the gastroscopy and gluten thing...
Glad to see you're both feeling so good on the GF diet.
