I’m somewhat similar, but I never feel sleepy even if i spend 24 or more hours awake, i will feel extremely tired but never like some people falling asleep in their desk or while driving, i need to intentionally go to sleep and it will be instant, 6hs is my optimal sleep time and most of my family from my mother side is the same.
