I have recently been diagnosed with lead, mercury and thallium poisoning. Info available in NZ is limited! I have started on Dmsa 3 days on 11 days off with loads of nutrients etc in the 11 days. First time I became very ill after taking 800mg over a day and had to stop but am trying again on Friday at lower dose of 300mg per day. Would love to know of another using similar method and how they got on.
