I see. I had a similar thing where I was traveling in Europe and during the trip every day it was getting better, where towards the end it was only noticeable when I woke up at night my legs would vibrate, but then I got back to the states and the first night was ok but every day after it got worse and worse again and now its back to how it was originally which is super disappointing. I wonder why it changes like that? If there was brain damage wouldn't that mean you could never get to the great state? So I kind of wonder if something else is going on.

I found out I have high levels of mercury, 31.8 ug/L in my blood whereas 0-15 was considered normal, so it could be that. I also wonder if it could be a pinch in my spine as my neck has always been pushed forward due to years of computer work.

When I'm tired or drink a lot of coffee it definitely is worse than when I sleep a lot. But it's hard to sleep a lot when you wake up with your whole body vibrating and then it becomes hard to go back to sleep.
