Just wanted to say don't beat yourself up for what you feel was wasting time (though I know how easy that is to do!)...it's all a learning process. Chelation is a such a minefield.....there's so much conflicting info out there it's easy to get caught up in trying different and sometimes unsafe things. It's my personal experience too that heavy metal toxicity affects your judgement!
Did you ever have a hair test?
Also just wanted to say that jaw clenching can be related to parasites, though of course that's connected to metals too.
Anyway, glad you're feeling much better, take care :)
