Patricia, Just thought I would mention this for what it's worth. I've just figured out I'm gluten sensitive. My GP did the blood test for celiac, which I kind of figured I would have, since it's an autoimmune disease, too, and I've already had Graves' Disease, and MG. But it came back negative. But I've been staying faithfully on the gluten free diet, and was amazed to see how much it has helped the MG. Or rather, how much of the fatigue I was ascribing to MG was probably coming from the gluten sensitivity. It might pay you to just try a gluten free diet for a few days to see if it helps you at all, especially if you have any of the symptoms associated with gluten sensitivity.
I'm still elated over the change I got from going gluten free. I hope it lasts for me, since I feel like it is helping me to get a life back!
Hugs,
