According to Dr. Cutler's book, Amalgam Illness, mercury interferes with the body's ability to use magnesium. This can cause muscle aches and pains, muscle stiffness and soreness, muscle cramps, and even heart problems. Extra magnesium is a chief recommendation for anyone with fibromyalgia and especially if you have or have had amalgam fillings. I would definitely try taking extra magnesium. I use a product called Magnesium Complex, which contains 2 forms of easily-absorbed magnesium. I can really tell a difference. No more sore/stiff muscles when I wake up. I can also work at the computers for hours and hours without getting a sore back or stiff/aching shoulder and neck muscles. You can even open the capsules and pour the contents under your tongue for faster absorption.

Hope this helps. Keep us posted!
