I tried the gluten/dairy free diet and definitely feel better. I can feel it pretty quickly if I eat a moderate amount of one. Especially dairy, I tried a lactose free icream but felt like my throat was closing in, so its something else in dairy.

If you haven't had either for a while you could just try gluten, see if it makes a difference and a few days later same with dairy.

I still need to take my medications, hasn't changed anything about that. Just feel better and I've lost 30 pounds, back to what I was when younger.
