I know that redistribution hits everybody after each round. Once you stop the chelating round, the still free floating mercury gets re-absorbed again. This can increase symptoms for some. Some of the mercury may come out on it's way, as the rest is re-absorbed until the next round. Just as you stated.

I found it at times quite intolerable to stay on a round for long enough. Andy's was the most stable, but I experienced increasing exhaustion and aching and at times found revolting, very ill. I can relate to what you're experiencing and yes I believe it is mercury being pulled out and moved around as well. Though it may also be some minerals that maybe depleted in the process too.

Things should improve over time. It takes a long time though. Often there is so much stored mercury that the more you pull out, the more you realise is there. It was a shocker for me to find out how much mercury was in my tissues/organs. And how difficult it was to get enough of the stuff out to start feeling human again.

Antioxidants were of most importance to me! Vitamin C, vitamin E and selenium were actually the most common ones I used. I had good quality ones and they worked. I really needed them desperately, not just because I was poisoned and mercury uses up antioxidants, but also the stress of chelating too.
