Hi Orv. The problem she may be having with MMS1 is if she has little or no stomach acid, residual MMS might cause those side effects.
Trying CDS seems like a good idea. Yes, start with 1ml of 3000ppm CDS in a glass of water and let us know if she can tolerate that. Don't add DMSO at first, wait and see how she tolerates CDS by itself. I think you have done enough clay to get rid of any possible fungus/mold.
Since she has so many issues, she will have to keep CLO2 dosing low for some time. Even 1ml of CDS might be too much.
