Boyd Haley in one of his talks says a hormone receptor involved in the stress response system (ACTH, FSH, etc) holds onto Hg about as well as anything can. It is hard for me to imagine how our little dithiol chelators could pry Hg away from that receptor with its many thiol groups. It is no wonder that so many of us Hg toxic folks have poor stress repsonse.
Interestingly the member, nohg4me, is a middle aged female that took longer than anyone I've heard to get near 100% recovered--8 yrs! She was nearly be ridden with CFS, etc when she started. She used to have a good blog site but I suspect it was affecting her professional career.
