When I wake up, I can barely function. I can't do simple math, typing and writing is very difficult, and I come off as crabby because everything, every sensation hurts a little. Lights, sounds, and even smells make me irritated. I vaguely recall this happens most mornings I have to get up on weekdays. I can also recall that I only remember about 20-40% of anything that I do, say, or hear.
Literally, many mornings I "wake up" either at work or on the Metro with little to no recollection on how I got there, only a vague sense of events. I have been told I carry on normal conversations and do mostly normal things.
It's a little scary, like I have a double life. And my other life is dull.
