Sit for a couple more hours, playing games.....that should help.
I hate it when I'm emp'd and my HUD goes all screwy. Ruins the rest of my day/night.
It gives me nightmares....where I'm talking to people, or I'm at work etc.
The worse one is...people are slowly walking towards me, saying things like "How are you?"......... "Good morning".
I try to strafe but that's all screwy too.
I feel your pain.
That and/or I've had too many beers.
