Timaca, thanks for all the information and for documenting all of your experiences, which are great to have as a reference point (as well as everyone else who has shared on this thread). Cloud, I was referring to the aggressive ideas (based on work in the autism community) in the “GI Biofilm/ infection/heavy metals” thread: http://www.forums.aboutmecfs.org/showthread.php?2123-GI-Biofilm-infection-heavy-metals which seem to rely on chelation to dissolve the metal and mineral-based “fortifications” that the pathogens (yeasts?) are hiding under, combined with pathogen (yeast)-killing substances and binders to mop up liberated toxic metals. It all makes sense to me, except for the fact that nobody on that thread seems to have had positive results—it seems to me that people on that thread have liberated pathogens, metals or whatnot, but somehow fell short of achieving a positive result for some reason (some have had herx or other strong reactions). So I remain gun-shy for the moment.
