Approaching 6 months - what's the "dump" gonna be like? How to prepare?

I've seen many sites where people say that after about 6 months, there's a sudden "mercury dump" when chelation symptoms get worse, because the body is tossing out mercury at a much faster rate.

Well, I guess in a way that will be a good thing, but what is it like when it happens? Who here has been through it, and what can I expect? And how do I prepare - what can I take to reduce side effects while still getting the benefit of the big time mercury dump?
