Am I functional? Barely.
I haven't had a lot of sleep for a couple of days, and last night was totally miserable (as the previous post attests). I came in to the office for work today, though I had considered not doing so. I'm doing exactly what I have to do here for work this morning. And have already managed to take a 15-minute nap.
I have no idea how the rest of the day is going to go, but things will certainly be interesting.
