Feeling more positive today in viewing this as an intolerance issue. Explains so many of the symptoms. So from today I am back on antihistamine, quercetin, flushing niacin, vit c, d, turmeric, and hopefully also collecting Famotidine from pharmacy later.
I will try way lower histamine foods, but doubt I can fully follow the diet wholly. I've definitely had periods where I can eat foods higher in histamine with no issues, but it makes sense that it builds up and then explodes.
I've also read that osteogen releases histamine, and progesterone lowers. Would it be crazy to try the progesterone-only contraceptive pill? I've been meaning to sort out my contraception anyway!
