I have a feeling that Prism is actually quite a nice person for whom something has gone terribly wrong. You can tell from reading some of her older posts.
I was just reading that she was high-dosing Magnesium. Mega-dosing actually. Long before I ever took iodine, I had trouble with delusions when I upped my magnesium supplementation to 800 mg. Her thyroid history is similar to mine, and her posts say she was upping to 3 grams of magnesium. I'm thinking that my reading on magnesium indicated 1 gram is the upper limit for women.
