Hmmm
It seems that I've turned into a morning person of a different variety. In this case, I've been avoiding sleep for the past week in the form of staying awake until 1 or 2 AM. When I wasn't going in to work last week I seem to have compensated by sleeping in to an unreasonable hour of the morning, but I haven't been able to do that this week, and I don't want to waste my time in Chicago with that this weekend.
Eventually, I suppose I'll be back to a normal bedtime just because my body is completely exhausted.
