The longer you are grain free, the less inflammation you have so usually the so called "allergies" improve a lot. This takes time.
I can tolerate pollen from grass and trees much better now. So far this season I am not sneezing and not feely woozy. My nose does run a but and my eyes do water a bit, but not very much at all. Just before I tarted this way of eating, I could barely drive with car windows open because if someone was cutting their grass, I would be sneezing very badly and my eyes would water enough so that I thought I was crying. No more!!!!
My doctor said :allergy shots! They didn't work all that well. Now, no shots, no Benedryl and I am nearly allergy free. (98% better).
