Sleep deprived

If I am going to wake up at 2am in the morning and find myself unable to get back to sleep for hours... yes, hours... I would really prefer that it happened on a Friday or Saturday night when I have the following day to sleep in and catch up on the sleep I missed out on between the hours of 2am and 4:30am.

(Not even my sleep machine could save me last night).

Sunday night is a particularly bad night for this to happen. I hate Mondays to begin with, and I have a busy work day scheduled today. And now I'm very tired and very cranky (crankier than usual).

My tolerance level is low and I'm not mentally equipped to deal with the monkeys that are trying to run the zoo.
