I feel better too on DMSA..but don't know.

The Lyme cysts are constantly hatching new spirochetes. This process releases Hg and possibly Pb into the system.
The spirochetes need to find a new home, your cells, and begin to probe for weak cell walls and use infectious plasmids as well as Hg to weaken you just enough so they can slip into the cell.

When this occurs in\on the Heart you get Ventricular fibrillation since they actually use electrical current to probe for weak cells. If this happens in your brain you get all sorts of concentration issues...always feels like you lost a second or two of thought…

…or as Dr. Klinghardt put it in "Lyme without...";
It is a constant cycle of treating Lyme and removing Hg

Personally; if you are chelating and NOT treating for Lyme you will feel horrible because too many spirochetes are trying to find a new home without having Hg available to weaken your system. If you are treating Lyme without chelation then eventually the Hg will make it all feel worse.

NOTE: There is nothing wrong with staying on DMSA; the only issue is that you need to cycle the ALA so you don’t become too copper toxic. There are ways around that but so far NAC is the best copper binder yet stirs up Lead which can be hugely problematic.
We used Cilantro tincture on the days off ALA.
