I don't know if you had a good practitioner when you were with ARL, but I find that makes a huge difference. He or she should be able to explain why you were on Limcomin even though you were copper toxic. I also have been high copper from the very first test, and I was on Limcomin. If memory serves, I believe it was due to a NA/K inversion. Once that was corrected, Limcomin wasn't used. If you decide to try ARL again and want the name of my practitioner, PM me. He has been great to work with.
