I am getting these too. I have also have twitches in my back, hands, stomach, just about anywhere. I noticed my right calf twitching just today, while I was sitting here on the computer. It drives me crazy. I can't remember, it is good or not to take the magnesium while you still have your amalgams in? Isn't there a certain type you have to take, and can't it make some people sick? I have heard of some side effects of taking magnesium for some people.
