...and I appear to have slept in my clothes. They may be someone elses' clothes. Additionally, I have gone blind and could possibly have contracted some tropical disease.
What did I say about leaving when you've had enough? You've probably got a hangover. Plenty of fluids and the analgesic of your choice will probably do the trick, but if you really need medical assistance, get someone to find a steward who will radio for a first aid team. The first aid tent can be found at the top of the main field, but help is available 24 hours a day. Oh, and if you have a blinding hangover, don't go to sleep in the sun. You'll wish you'd died.
