i need to build energy and flush out toxins and heavy metals. that's what's causing all the chronic symptoms is the poisons in me. cognitively i'm not doing very good so even that simple article is difficult to understand.
I think the good news is that you have decided to take responsibility yourself and accept the decision making, not placing that entirely in the hands of the so-called experts.
Heavy metal detox is not something to embark upon without knowledge and planning. It's easy to lose one's way on the path to wellness. Ascorbic acid has a wide safety margin. But chelators of heavy metals do not. They are risky business. One risks permanent damage. I strongly recommend becoming familiar with the Cutler Protocol:http://onibasu.com/wiki/Cutler_protocol
A big help will be the case reports and firsthand accounts of others who have travelled the same road as you:http://health.groups.yahoo.com/group/frequent-dose-chelation/
One chelation victim started her own website; it has patient reports, voodoo doctor stories, and other info about a certain chelator (DMPS) you should probably avoid:http://www.dmpsbackfire.com/default.shtml
