I too have been troubled by allergies, and think your explanation has some more truth. But, do you think its possible that you could it backwards? that is, massive allergic reations deplete the adrenal glands over time? Or, how about individuals who have a few very stong allergies like shell fish or peanuts. I know a girl who literally got third degree like buns on her food because a small piece of peanut shell touched her exposed food for just an instant. The allergic response is so exagerated that the adrenals could never hope to control it.
I don't mean to attack your explanation, just discuss. you obviously know health, so, I appreciate you insights. Like Neo, I have struggled with allergy issues for some time.
