24 hours

I just realized, I've been awake for 24 hours now. When you are awake a lot, it's easier to stay awake like this. When you are not used to being awake, it's difficult to stay awake but easier to fall asleep. When you are used to staying awake, it's more difficult to fall asleep or to stay asleep. Your body gets used to being awake even when you are tired. Your body feels that being tired and awake at the same time are normal. If you have a job where you are constantly having to keep yourself awake, then when you are home and about to fall asleep, you get this body jerk that wakes you up. It's really weird and probably not good for you.
