I think I got barely five hours sleep, and waking up early felt just awful. But as I gained consciousness and was figuring out who I am, what day it is, etc., I remembered that tomorrow I have to be up even earlier for another day of rehearsals and a spring concert at the high school, and I simply won't make it through that if I don't get up immediately and stay awake all day and get plenty tired so's I can get to sleep at a very decent hour tonight. So here I am -- on the job, so to speak, but not too alert.
More coffee!
