You've started chelating already?! Did you get the book?
You will feel fine initially as some of the burden is taken off the body but be careful not to rush things. Did you join the freq chel group? It's a good idea to do so to get support from people who are going through it in case you get stuck at some point....obviously it's your choice about how you go about things :)
How much are you taking? You know some people start on much lower levels than suggested in the book eg 15mg of ALA and 20mg DMSA.
Anyway I'd better shut up or I'll end up sounding like your mother lol!!
Let us know how you get on and if you feel any less deranged ;)
