If you are having heavy metal tests done, be careful about trusting the results. They are infamous for being inaccurate.
I switched between cilantro/chlorella and the Cutler Protocol. Sometimes I did one, and sometimes I did the other.
My yeast symptoms did get a bit worse while I chelated (an important clue that there was a link between them), but the symptoms became less and less as I continued chelating. It took me about 6 months to feel my first real improvement.
