Maybe It's Mercury
I was very lucky to come across information about Andy Cutler on the internet. He got sick himself and was fortunate to have just the right education to read the medical textbooks and studies to figure out what was wrong and what to do about it. If you get nothing more from this website than the name of the below two books, you will still be way ahead.
Andrew Hall Cutler, PhD, PE is the author of Amalgam Illness: Diagnosis and Treatment and also of Hair Test Interpretation: Finding Hidden Toxicities. These books are described at www.noamalgam.com and www.noamalgam.com/hairtestbook.html . He has a PhD in chemistry from Princeton, a BS in physics from the University of California. He is a registered patent agent and a licensed professional chemical engineer. He currently works as a detox consultant as well as writing books.
