They were mild food allergies , really more systemic "intolerances". I don't want to give any one the impression that I am talking about say, a peanut allergy where if I ate one I needed an adrenalin shot in minutes or go into shock... They were more just the kind that gave me raccoon eyes, and made me feel tired a lot.
Anyhow, they went away within the first 3 months, along with most of those other things I named.
