I hope a sleepless night won't muck-up my blood test later. Blobs of hemoglobin snoring at the bottom of a test-tube... "I'm sorry Mr Rimmell your blood was asleep for the test so we had to fail it."
Gave up trying to sleep. Finished reading Thud (again). Last hour I've been looking at victorianlondon.org.
Then I found Victorian Google Earth London... I particularly like the "Buildings that no longer exist" feature. What a pitty we can no longer visit The Eagle Tavern Pleasure Grounds.
And now 3 hours before I should be getting up... I feel like I could sleep.
