Thanks for the info!! I have had GI issues since this all started.. and have family members with celiac, so I went gluten free.... my GI issues resolve with the diet.. yesterday I ate something I shouldn't and have been paying for it - but my muscles are apparently angry like My GI system, I had been feeling great, but now feel so weak... can't swallow well again and walking up the stairs feels like a marathon! So, I'm a big advocate of the Gluten free diet!
