Yeah. I can stay awake for more than 20+ hours but it's hard for me to fall asleep and stay asleep for a good amount of time. It's also hard for me to go back to sleep once I wake up, which sucks since I'm sort of a light sleeper.
I have periods of weeks where I just can't get to sleep no matter how much I sit in my bed and try. It is immeasurably frustrating because I go to bed so early and just sit there trying to sleep and can't.
