Gluten makes me feel worse. I learned of a study in dogs where the dogs fed gluten developed a diabetic condition. I found this out after having to spend a couple hundred dollars a year on medicine for my dog with pancreas failure. I was feeding her a gluten spiked food. On the brighter side, because of that I didn't have to worry about the tainted dog food. Cut out the gluten, and see if it helps, chances are it will.
