Definetally a night person, i can stay up really late, wake up early and not so much feel it, after a while it all come crashing down but that's pretty rare, i had some pretty bad insomnia up until about a year ago, so i was used to staying up late anyway, havign said all that, it is ill adviced to wake me up before i want to wake up, or for anything that is unimportant, i've been called a grizzly bear because i've been known to maul the person trying to wake me, or in rare cases, pull them into the bed and trap them in a vice like hug.
I have what i call 'the 10 minute rule' it states that in that ten minute period after i've woken up, you should avoid giving me anything that sounds like an order, or giving me any kind of information, as i am likely not to care and forget it all.
