Mercury, huh? Wow. I thought I had dealt with that already, but maybe not. I had my Amalgams out years ago and did some chelation with supplements, though I can't remember what I took. More recently I was on Modifilan for awhile, which is also supposed to help. Did the cilantro pesto for awhile, too. Maybe I'll have my homeopath check me for mercury again, I'd rather not pay for a formal lab test, but might be worth checking for metals at this point.
