Thanx for the well wishes, I enjoyed reading others perspectives on the histamine and copper issues. One thing I must warn about though that was mentioned....arginine is a known trigger for major schizophrenic episode. And frankly high histamine can at times feel very close to schizophrenia because of the brain fog and derealization....my suggestion is if you are using arginine or anything like it go slowly and conservatively. I would first try tyrosine....and also TMG is a much gentler way to manufacture SamE and combined with methionine helps high histamine people produce much needed adrenaline that gets depleted combating histamines...this IMHO is what causes a "crash"
