experiments in sleep deprivation

I just got back from my trip, and I had some interesting times on the drive. We decided to drive through the night since the AC isn't working, so I was a bit short on sleep. That in addition to being short on sleep a bit for the whole week led for some interesting times. I know that I get kind of loopy when I'm sleep deprived, but I'd not experienced it in some years. Last night my moods were all over the place, changing from one moment to the next. I was emotional and crazy at the same time. It was kind of fun, but I'm glad for sleep.
