My brain had different ideas. It decided now was an ideal time to feel productive. Lying in the bed doing nothing but dozing? Out of the question! I needed to be up, sorting out the flat, setting the world to rights. Forwards!
I've decided to sort this out by getting drunk. I suspect that I'll regret this later, but I haven't got drunk for absolutely ages, and (in my slightly sleep deprived incoherent state) I have a vague idea it's a good idea. Besides, some of the drinks have a best before date of April 2003. It's about time they were used.
UPDATE: Well, I finally got to sleep at about 3:45, so at least I got four and a bit hours sleep. I still feel somewhat drunk, though. This too will pass...
