Night Person is a 'perk' in Fallout 3 and Fallout: New Vegas that you can take on levelling up, giving you +2 to both Intelligence and Perception. I bring it up because I think I have this in real life. My brain always works better at night. I've always done my best work in the evenings, from writing short stories in high school to essays at university. During the day I can't get anything done.
A few days ago I was trying to get over my late nights and late mornings by going to bed a little after ten. I was feeling fairly tired so I thought I might be fine. Unfortunately, I woke several times during the night, didn't sleep well at all and still ended up waking at 10.30am. Epic fail.
I spent much of yesterday working on something for a writing competition. I had a lot of difficulty with it because the word limit is 250 words. I redrafted several times and still didn't get anywhere. As soon as I lay down to sleep, however, at the quasi-realistic time of 1.30am, my mind was abuzz with ideas for it. I couldn't sleep knowing that these ideas might be gone in the morning, so I had to jot them down in my notebook, but that wasn't enough to settle my mind so I had to watch TV for an hour to calm myself down.
Anyway, back to it.
