There might be an adrenal angle to some of these. For several years I used to get depressed after consuming dairy products. It was most pronounced when my adrenals were at their worst. I knew I was somewhat lactose intolerant, but didn't know that I had a sensitivity to dairy and by consuming it was further burdening my adrenals. I bought some whey protein and tried to use it, thinking it was only barely a "dairy product," but I felt that old depressing feeling again.
The Depression after iodine, Colloidal Silver , and zinc are are very probably die-off. The calcium--is it alkaline/alkalinizing? causing the candida to multiply? Then again, when I eat something with Sugar and feed the candida I feel sleepy. Doesn't feel like die-off...
