Trying to crank my eyelids into the nominally open position. Woke up at 2:45, didn't drop off again until 5:30, spent most of the time in between trying not to cough or sneeze so as not to wake the missus. Turned out later that she'd been awake most of the time so I could have.
Two pints of tea and a coffee later I'm still anæsthetized.
(Note erudite use of æ: take that, bloody Webster!)
