I sent her a detailed message asking about whether she had fillings etc, explaining to her the basics (including that while it sounds wacky at first, amalgams are NOT safe, because Mercury is a neurotoxin etc) even included a link to "What I've learned about Mercury". She said she wasn't sure about the fillings but thinks she had them removed before she became pregnant a number of years ago, and I replied that having them reomoved in an unsafe manner could have caused a large amount to be released into her body thus chelation is something to look into... which makes me think that if she didn't know anything about what I had written, she probably didn't have them removed safely etc.
Overall she didn't seem all that interested in the notion, though I HOPE that she becomes interested.

I think some people, when dealing with chronic health problems, become so tired of not finding a solution that they just sort of grow deaf to other possible explanations. IE because seeing regular Drs., getting accupuncture etc haven't helped her, she may just be stuck in the misery.
