My brain pulled an energizer bunny on me last night, wide awake, bouncing around like it wasn't night at all:
I tried every trick I know to get it to relax and go to sleep, but nooooooo. Nothing worked, until I realised three a.m. was approaching on the clock with no end in sight, I took a pill and that knocked me out for a few hours.
My god, brain, why?? It's not like you don't need sleep, on the contrary, you need it more than ordinary humans, so why this energetic fest? It's an aspect of my mind I'll never quite understand.
And the advice generally given to insomniacs --if you are not at all sleepy, get up and do other things-- is dangerous because I am, to my horror when discovering this, perfectly capable of falling asleep standing up (and then falling over) ten minutes after not feeling sleepy at all. So no, better not.
I'm seriously happy science has invented knock out sleeping pills, though.
