I've had vaccinations as a child and been drinking tap water for a long time (drinking mainly Berkey filtered water now with reverse osmosis) so I most likely have at least some mercury/lead build up in my tissue. I've read that this could lead to long term side effects which I aim to avoid/minimize.

I think feeling good is relative, I may get done with this and feel even better than I do now and realize how crappy I felt before, or I may not feel any change- either way I'll have peace of mind.
