hi veggiemom : I decided for now not to continue the dmsa ,It really messed me up on my last round almost 2 weeks ago ,I felt like right before amalgam removal ( don't ever want to go back there again,NEVER !!!!!!!!!) the good thing was i started taking activated charcoal again about 4 days ago and am starting feel much better , I stopped taking it about 2 months ago , and that was when my detox symtoms started to get worse ,so for now will be doing natural detox and taking my old faithfull "activated charcoal "
