DMPS is a very powerful and effective chelator.

I noticed one thing in particular when I read the stories at the dmpsbackfire site a while back, and DeeCee's story above also reiterates the same thing, just about every single bad testimony of DMPS includes the following line just like DeeCee includes it above:

I was extremely ... constipated.

The DMPS works. I think most of these people have a different problem which complicates things, and will complicate things no matter which form of chelation they try.

Any form of chelation, if it's working, makes you feel tired btw. And your doctor is right, if it were the DMPS causing the problems you would have noticed the same day or within a couple days at most. Mercury or some other heavy metal/toxin is causing those symptoms DeeCee (not the dmps which obviously did you cause to dump) but only because you are not eliminating and need to do a colon cleanse first. You are blocked up. If you are going to chelate, you need to truly dump the metals, not let them sit in your colon all week and then recirculate.

I still have amalgams too btw. And I can chelate without a hitch. I feel really good after 18 months or so of it also, amalgams somewhat still in. Really good. It's true what Hal Huggins says, it's in your head (your mouth actually) but he doesn't tell you... it's not all in your head, a great majority of it is in your gut. Clear your gut and you will do well with DMPS or any type of chelation for that matter/ DMPS is simply the quickest, expect big dumps at first if you use it.
