I think my real problem wasn't kidney but liver. Kidneys were stressed yes, mostly due to severely congested liver. Also, mercury was causing so much inflammation in my organs.
I have done now all of schulze's cleanses, some of them twice or three times. Much better, but every month the yeast flares up and so does the inflammation.
I tried on round (Cutler chelation protocol) with DMSA and my liver/kidney couldn't tolerate it....fingers swelled up. I started at 25 mg. So, I will keep using ALA as I can tolerate it just fine.
I also switched to low-sulfur diet as I am high cysteine and that seems to be what causes the yeast flare ups/inflammation.
