Asleep on the job...

Waking up this morning required a guargantuan effort. I shlupped to the shower in the hope that the hot streaming water would wash the sleep away. It didn't. The drive to work was done on 'automatic' and despite multiple coffees - I can't stop yawning. You'd think that I partied hardy all weekend - but I didn't! It was a pleasant weekend where I relaxed and went to bed at the same time as I do every night. I can't concentrate, I am totally useless. Someone please wake me up!
