David:
Evidently this is quite popular now and some of those on the
list are drinking it daily. I am using a Britta filter and
trying to keep it out of my water supply, but please let me know
if it is getting in and the telltale symptoms are appearing.
Obviously I do not know everything, as I even suggested the
very, very ignorant idea of using epoxy (ugghhh!) to cushion a
rare stone.
