Have you gone to the Dr to be tested for allergies? I have had it confirmed now that I do have a mild allergy to wheat and dairy through an allergy test. Might be worth you having this checked out.
My naturopath did all my allergy testing and also tried to fix some of them. Most of my problems were with sugar, milk and acidity in my body. Who knows if it worked! The thing is that I can eat these things without problems most of the time.
