Probably fairly sleep deprived. I'm older now, but I never did fall asleep easily. And I've always had night terrors and violent nightmares, so I wake up in panic most of the time, and it takes hours for my heart rate to go down enough to fall asleep again.
I guess I average 4 to 5 hours of sleep on a good night. But, I don't feel sleepy during the day, my heart races all day long also, I think I'm just built not to be able to settle down.
