How many mercury fillings did she have? I had 25 of them. I struggled to do chelation, and had to keep stopping, as my sleep was already too disturbed. I had the last of my fillings replaced 3 years ago. At first I started feeling better after a few weeks of chelation, but then had long periods when I felt much worse and couldn't chelate. Now I am chelating again, however I find it hard to complete even 3 day rounds. In the three years since replacement, I think I only did around 50 rounds, and none of those were longer than 3 days. Someone needs to develop some patches or timed release chelation pills, so that people can still try to get decent sleep while chelating.
