What is wrong with me?

I got woken up by work at 2:15am this morning. I am still up, but not for long. I only have 5 hours of sleep until I have to get up again. (DB Server. Hardware Failure. Spare part not available. Work around created by charming and resoureful engineer. Outage for repair scheduled for 3am the next morning.) So much for my new goal of using the CPAP more often...
