Are you an early bird or a night owl?

i sometimes get all out of phase --- like when they change the clocks,, that messes me up big time --  or when i change time zones ----- in chicago i always got up at 6am every morning for months.....  i have no idea why ?

I'm up at 6 most mornings, bed at 10 although I can go later if I need to.

I have phases at the moment I'm an early waking up naturally at 7am and im fine all day other times I'll be up all night and wake up in the afternoon it was terrible when I was working in the city and had to be at work for 8:30am and I couldn't sleep until 5am

Much prefer the early bird phases 

night owl if not working but when working i go to bed at around 12 midnight each night. Mornings are really hard for me. I predict many night owls.
