Woke up with a hangover. At 3 am. Tried sleeping downstairs on sofa but got too cold and came back upstairs at around 6. When I woke at 6:30 and still had a headache I took some ibuprofen. So miraculously when I woke up properly at 11:30 hangover completely gone. Nifty.
Must find some lunch before I head over to Simon's for B5 this afternoon.
