The science of sleep

So has anyone else ever had a really sudden, weird bout of insomnia, when there's nothing particularly wrong in your life beyond the usual day-to-day worries? Insomnia lasting weeks at a time, where you can only sleep anywhere from 45 minutes to three hours a night, and no matter how exhausted you get, as your short-term memory vanishes, your muscles start cramping from exhaustion and you have a permanent headache, you still can't sleep? Even with the aid of over-the-counter sleeping pills and every other combo of drugs and alcohol you can think of? Even after you've convinced your doctor to prescribe you something heavier and it still doesn't knock you out? After you've tried every gosh-darned thing you can think of and more, and are starting to think you may never sleep again? And you have started wondering what you should tell your employers because if it goes on much longer you will cease to function and have no valid medical reason for it? Yeah. I think I'm finally coming out the other side of one of those bouts. I've had two nights in a row of drug-free sleep now. For which I feel a tremendous sense of achievement, which is ridiculous as it's something you should be able to take for granted, isn't it?

Anyway, I'm going away for the bank holiday weekend. Want to know where?
