Too late. Sure wish I had that info when I just started. I've already had 13 DMPS treatments and wound up with severe chest, kidney pains and migraine headaches. To which my dr. said "you need 30 more!" What a lunatic. Well, I don't see him any more and I am now on bio-chelat and clay baths and all of my aches and pains have disappeared. I've read http://www.dmpsbackfire.com a few weeks ago and that is when I made a change. Thanks anyway.
