I think the second stage of suffering can occur to most mercury toxic people. It's just the body's way of tryng to dump it's storage of mercury (once the last amalgam has been removed). For some reason, it does not usually occur right away, but instead months later or even up to a year or more later.

It can be reduced and quickened by safe chelation so that the blood gets cleared faster.

It's very difficult when yu're trying to do all the right things and you feel like garbage. If you're a bag of bones and you feel your diet is too strict, you could try including more fatty things in it and a bit of fruit if you tolerate it. Sometimes one has to do that, but not overindulge in junkfood. I have things like meat with the fat left on it and plain acidophilus yoghurt (full fat) and raw nuts and things. If I didn't do that, I hate to think what weight I would be. I'm thin enough as it is.

(and yep I've experienced the second stage of suffering, it occured about a year or more after my last amalgam was removed, prolonged and nasty and I did not know about the importance of regular safe chelation, I just did bits of random detox).
