Moose, i don't have problems with racing thoughts any more but since before I could remember my brain refuses to shut down on its own. I have to role play things in my head to quiet it down enough. when I was a kid I used to take trips to the moon or explore the jungle. I'd slowly make my own path, cutting vines out of my way with my machete. Every so often I'd take a drink of cool water from my canteen. When I'd finally discover the hidden ruins I'd been searching for I'd pick my way through the buildings. It may sound weird but it really works.
