Another couple of thoughts. Bex is absolutely right about diet, but I have seen some big improvements in the past week by adding HCL pills with pepsin before meals. These really help with breaking the food down into the protein our body can use. They make the stomach more acidic, and help kill off candida too. I had a couple of uncomfortable days with die-off, but persisted, and am definitely feeling better now.

Shaky hands might also be low cortisol, Nina. It's very likely your adrenals have been affected by the mercury. Do a google on adrenal fatigue, and see if you can find the symptoms of low cortisol. You might want to support your adrenals and help them heal by taking adrenal glandulars. These made a big difference to me, although my adrenals are very damaged now, and I don't hold out much hope of them recovering fully. I wish I'd known back then what I know now...

Best
