Hey there, I know how you feel. You are not alone. I had an auto accident the day OJ run the highway. And I had another bad one May 2010. This post concussive nightmare is just that. I don't sleep without horror upon waking. I have neuropothy and lots of pressure in my head. I thought things would settle down. But to no avail as of yet. Seems positional changes laying on left side vs. right side vs. standing affect my state of being??? Anyone feel that???
