Hi mercuryfree, migraines can indeed be caused from amalgam toxicity. My Mother now gets them all the time and she has a mouth packed of amalgam and she has gold too (never combine metals in the same mouth). since gold, she's had worse headaches and migraines. Gold or other metals increases the release and uptake of mercury from amalgam. It also caused a galvanic response. Can worsen people's amalgam issues ten fold. Same thing happened to me when getting braces on my teeth and that was the final straw which sent me into chronic ill health. Even though they were removed, I was sick from then on and had to find ways to improve.

Andy Cutler recommends Saunas a way of detoxing mercury. He compares it to being as effective as a round of chelation. So you're doing the right thing. That's if you sweat properly, which it seems you are now doing. Good sign, I'd keep it up. Not overdo it, because you can lose minerals/salts through sweat apparently and need to recuperate, but I'd definitely do it regularly within reason.

You'll find exercise may help too, but be careful with overdoing it, because it stirs the metals up as well.

I hope that you will stop getting migraines! Perhaps ridding yourself of amalgams maybe the start of that. I sure hope so.
