Yeah, enough sleep. Like 15 hours. Worst aura in my life, completely shut down three quarters of my left side visual field. Followed in a matter of minutes not by a headache but complete inability to think and — this is really weird — a diminishment of my colour vision…The whole thing was triggered by the ruby laser in my optical mouse, if you can believe it. Before I went home sick I marched over to IT and replaced it. Woke up around 4, glanced over Katie’s shoulder at the computer which triggered visual effects AGAIN, this time on the right side, followed by tingling and numbness down BOTH baby fingers, so into the hottest bath I could stand, and lots of painkillers. Back to bed and up at 6:30. Feel like crap but I should be okay at work if I don’t move suddenly and nobody shines a light at me or yells in my ear. Gotta sign off, my fingers are tingling again. Must have caffeine. mOm the package arrived.
