And casein, too! I've managed to switch to raw goat's milk yogurt, which I probably overindulge. You were right about histamines! Became super aware of constant itching the other night and Benadryl quietened it down 95% within minutes. As far as copper detox, goes, I always read when it starts it's a rough ride and you can't stop it only try to lessen its severity. But this pattern insomnia is my only classic detox symptom apart from severe fatigue, and it stops and starts abruptly as if to a schedule--regardless of what I eat. Will get the ceruloplasmin test next week and report back.
