So let it be.

Why can't I sleep normally?
Why am I nocturnal?

Everytime I want to sleep early, I can't.
Like if I have to wake up at 5, I can only
fall asleep at 3.45 or 4. What is this?
Usually I'll be on the bed around 11 plus.
It's like a routine. Toss, turn and check hp.
Come on la body clock.
