Awake but how?

I'm having one of those surreal evenings, where I'm awake but I don't know how. My head is swimming in treacle, I can't think straight, I should be asleep, there's just... things still to be done.

It's been a non-evening.

After-work was a pub we'd never been to, followed by a trek to other bars that we'd never been to but were too full so we didn't go in, finally ending up in the bar we were going to end up in but two hours earlier than planned. It was horrendous. I hated the place the second I stepped inside. I left straight away, and won't bother with it again. At least my knowledge of the layout of Clerkenwell has improved a little.

The state I'm in. How do I let it get so bad?
