Hi Pete,
You're not alone, I feel like you're my twin, as I've unkowingly struggled for a similar period of time with mercury, and I became a real basket case of auto-immune malfunctions that no one could explain, it was quite a goosechase, but I'm confident it's drawing near a conclusion. see my saga below.

I'm also a musician/producer from the Chicago area and look forward to hearing your song when you recover. This whole nightmare has been a great source of inspiration for my music as well, and for me music is the most theraputic way to express my frustration with the way things have turned out.

Here is a summary of my saga:

Best of luck.
