I'm an insomniac, and have been one since I was about five years old.
Usually I fall asleep around 4 or 5 in the morning. I'm either on the computer - here, or elsewhere; watching the tele (All night X-Files marathons on Tuesday and Wednesday nights! Whoo!); or just lying in bed, trying to sleep. f course, that means I sleep until between 2 and 4 in the afternoon. It's one of the reasons why I'm failing college. I'd be so tired I'd sleep through my alarm and miss class. Sleeping pills never worked, becuase even though I'd fall asleep around 10 pm, I was still sleeping through my alarm until 2 or 4 in the afternoon.
I got a new alarm, finally. One I could blast as loud as needed. And the cats won't let me sleep past 10 am without waking me up at least once, so that helps on mornings I have to be up early.
Otherwise, I attempt to be in bed by 12 pm on the two nights before I have class. (It doesn't normally work.) And when my boss gets in a bind and needs to schedule me before 11 am, I drug myself with sleeping pills around 7pm the night before, just so I know I won't be in a daze at work.
I'm definately nocturnal. If only I could find a way to stay that way without angering the family and missing school. (And a SAFE night job wouldn't hurt, either.)
