thanks birdlady! and yes, I'm pretty sure I have POTS too. my heat intolerance has not gotten better after chelating..probably worst if anything.

funny you mention DMPS. that was the first chelator I took but I swithced doctors because of location..it was too far of a drive for me. thats good to hear your heat intolerance is getting better with it! are you getting IVs or is do they have it in pill form?
