Badly, I haven't had insomnia like that for a while.
I can't figure out why; I had a good day yesterday and there was nothing on my mind.
Figured it out. I'd spent the past week performing every night and not being able to wind down until midnight.
That day I had an easy day, and my brain decided that I just hadn't worked hard enough, hence why, at 4am, it was going "It's noon, I'm telling you!" while I'm going "That's the dawn chorus, I'm telling you!"
Last night I slept reasonably well.
