I find myself to be more of a night owl, I love staying up late and just playing games ad stuff, What about you? 
I am definitely the same.  I try to get myself on a daytime schedule, but I just can't do it.
It can be tough, but I love being primarily nocturnal, its a good habit especially when you have to work late nights.
That is what happened to me.  I work a shift job and had the night shift for years, now I can't revert back.
Lol well they say people who are night owls almost always stay awake past midnight and even some extreme night owls may stay awake until just before or after dawn! 
Luckily it isn't that bad for me.  How late do you stay up?
Well if I  feel more energetic I usually stay up till 2AM or later , Io try to go to sleep at around 2-3AM at night though. 
Well I hope it doesn't affect you too much.
