wow, my son is 13 and his vision therapist was very thorough about him having an allergy. I knew he had allergies, but didn't know what. Years ago he was put on claritin for seasonal allergies. The season was (back to school). I just figured out that his dark circles would come back in Sep - March. That is when I would start making lunches with peanut butter sandwiches.
Also, I am relating his rage outbursts on the days he had the peaunut butter sandwiches.
He has no more dark circles. He had some peanuts with halloween candy, had a rage, and now is off peanuts, no rages.......
13 years..........
