Last week I turned nocturnal.
It was upsetting.
I couldn't sleep at bed time so I did the usual 'read some Pratchett as it's soothing'. When I'd stopped reading, I'd lie there for ages, feeling utterly exhausted but unable to nod off.
Then I'd write down what I was thinking about. Still no nodding off.
So a fair few times I came back downstairs and turned the computer on so I could do some writing/reply to messages/etc, anything to make me feel like I wasn't wasting time lying in bed.
Eventually I'd pass out on the settee at around 9 or 10am. I was woken up a couple of times and sent to bed, so I'd get around 5 hours sleep - otherwise, I'd only have 2 or 3 hours sleep on the settee.
So, I ended up nocturnal.
I think I've kicked it now, though. I woke up at 8:30 today after going to bed last night at 11:30 (due to my body saying I'M SO EFFING TIRED.) I just need to keep this up for another few days and I'll be right.
I'm at the doctor's on Thursday for a cervical smear and blood tests (b12, celiac, thyroid and one or two others but I can't remember what.)
