Bex,

Depends on how much Hg you have to begin with and how long you've had it. When you've had it for 40 years it seems to really hang on tightly. When I got a load of Hg from 9/11 it was much easier to get rid of, even thought this might be a case for using ALA but I went for the TDDMPS instead. No one is going to be able to tell you how much Hg you have, only what's coming out, and that is still not reletive to what your body load of Hg is.

Regards...
