Personally, I would bet my hands on this being mercury. Jinx's symptoms exacerbated severely since he had some amalgams removed, which exposed him more acutely to mercury. Since that time, he's been far worse.

The fact Jinx gets worse upon attempting to detox mercury is yet another indication.

And mercury is known to mess up thyroid function, as it messes up many other systems in the body. Usually people try and treat the symptoms, but mercury is so often missed as the underlining cause. Considering it's the most toxic metal known to man and in most people's mouths, I'd say it's playing a big role in most people's ongong health problems. As with many other toxic problems in the mouth like root canals, cavitations etc.

All of those issues are an ongoing source of potent toxicity to the human body.. Most of us have already gone down just about every other health avenue and came up with next to nothing.
