Just replying to my own message to anyone who sees this before I leave this site.
It turns out that I have some sort of nerve misfiring issue related to a pelvic injury I didn't know I had until recently. I had many tests run by an infectious disease doctor in Beth Israel in Boston, and I'm clear for parasites. I think the wormword stuff I was taking may have caused or worserned it, so be careful with the herbals. In any case, I'm sleeping better now, though it took months to get to the bottom of this. For the rest of you, double check and make sure you don't have a nerve issue! Or even some kind of misalignment (spinal) that could be pressing on something!
