You'll never get well again, if you dont remove your amalgams. However if you do, you'll likely get even more sicker, but it'll go away with time, hopefully. Early warning would be best, but there is no way to do that, as the earliest symptoms are so vague, and given that mercury toxicity is not recognized by mainstream medicine, what can you do?

I would have been glad if someone had said to me that your skin rashes and blurry vision may indicate mercury toxicity, so get your filling out. But of course nobody did it, and it took me nearly 15 years to figure that out for myself, with symptoms worsening slowly with time.
