oh i forgot to answer your question about copper. i never had any metal testing done, so i don't know. my ND did not think it was that important and we focused more on my food allergies , hypoglycemia,diet, and which supplements i would take. he worked well with me and was a real help. I don't think he wanted to overwhelm me. so many things, and when you are very sick it can be too much to deal with. that's why i said you have to make a commitment and stick with it. i was trying all these different things and nothing was working because i was all over the place. if you can have success in 1 area, then you can move onto another.
