The symptoms you're describing sound a lot like heavy metal symptoms. Are you doing anything now to chelate? If you are going to use a chelator like cilantro, make sure you use it every 3-4 hours and combine it with chlorella. Some people are concerned about cilantro being dangerous, but I've had a lot of progress while using it in this way without serious problems.
Otherwise you could try ALA every 3 hours (google the Cutler Protocol for more information).
Both of these chelators (ALA or cilantro) should be taken at least once during the night to keep the effect going and prevent redistribution. Do it for 3 to 5 days with a break for roughly the same number of days. Start off with small doses and work your way up.
This is just a rough idea. If you haven't already, find out more about chelating before you try it. It can be risky if not done properly.
