Hello All, I'm new here

A little background. I'm 42 yrs old and have been sick for over 13 yrs. I was told I had CFS, Lupus and last Aug I was dx with Lyme. I also researched a lot about yeast.
I'm now being treated for lyme but want to be free from metals as I do this.
Tomorrow, I'm off to the dentist to have 2 of my 6 filling removed.
Questions:
1- does anyone else here have lyme?
2- how do I know for sure I have mercury poisoning?
3- is there a VALID secure test for mercury poisoning?
4- how long should I chelate after I get the fillings removed?
5- Should I only get 2 fillings removed at a time and how long to wait in between for the others?

Any help would be great.
Also I bought some chlorella and am going to take it not just to detox metals but to detox my liver from the lyme.
Thanks all

Jen
