Are you a morning person or a night owl? (some are a combination of both!)
Uhhh....
That's a complicated one.
I used to just be all over the place. I used to sort of cycle around the clock, going to bed and waking up later than the day before, by a variable degree. And i'd just sort of gradually work my way around the clock until i ended up back where i started. So i was neither really.
But a few months ago, i tried to fix that and become a morning person. I'd like to think i've largely succeeded at that, although every so often my body will go "No you bloody well haven't, mate."

I've certainly managed to wake up at a reasonably early hour every morning since, so i'll take the victory and go with morning person as my answer.
