Is there some scientific reasoning behind seemingly unwanted, random crabbiness once and a while when you wake up?

This morning I was generally pissed off. I wasn’t tired. I felt fully rested. Even energetic. But I was annoyed at every little fucking thing. And there was really no reason why other than how I initially felt when I woke up.

For me, personally, I always happen to feel energetic if I’m crabby in the morning. If I wake up groggy or tired from a party night or what have you, I don’t get crabby.
