Steven,
I am concerned that you are painting the world as those who want to "denigrate any hope" (not me, my husband used supplements and an experimental ACE regimen, not to mention ongoing BiPAP titration) vs. those who want to try anything.
The value of "evidence" is that we have some sense of risk vs. potential benefit, as we'd expect to evaluate in any disease. When you have a headache, you don't poison yourself with alcohol or knock yourself out in hopes of sleeping off the headache, in the name of "doing something."
I am happy to hear you are verifying (hopefully with a "mainstream lab") the statement that your mercury levels are 25x what they should be, as that seems very suspect.
The statement that "if you do nothing, you can expect nothing" can be very dangerous when used as a rationale for procedures and substances that carry considerably more risk than benefit, which is why those of us who have reason to believe that the risk/benefit ratio is not favorable in a given case, such as removing fillings and undergoing chelation, feel compelled to say so.
Best,
Laurie
