Oh, yes I bet you are getting sick of white rice . Have you tried others kinds of rice? There is volcano rice, I think it's pink, jade rice..green, black rice "forbidden rice" etc. you can find them in health food stores and they have there own unique flavours. Also there are some other really interesting grains, I just saw one in the store.. Bummbeling for the name of it right now. http://www.lotusfoods.com/AllProducts.aspx here is a website so you can see what I am talking about with the rice.. they have so many kinds. I have tried some of them and they are pretty good. I thought there was only brown, white, basmati, sticky rice until I stumbled on these.

There is amaranth, which is a pretty versatile grain too.

Also say if you did have gluten intolerance or celiac it's very common for people with gluten issues to become lactose intolerant, and once off the gluten for a long time many are able to tolerate dairy once again. That's kind of interesting.

I hope you get some answers from your MD, not sure gluten would show up with allergy tests as it is not a true allergy, as in the body doesn't respond the same way with histamines.
