I posted a response about your sodium intake that you might want to look at. The response you are getting is indicative to adrenal stress which would make sense with all of your immune situations.
I know this all too well since I went into the 3rd stage of adrenal stress and collapsed on the floor with psych disturbances, actually I was full blown Cushing's. It took me quite some time to recover using the listed nutrients. I got the adrenals to stablize using the nutrients plus bovine glandular adrenal complex, which actually rebuilt the adrenal tissues. This is not well known in the US but used extensively in Europe.
