re: Anybody else just can’t sleep late?

I only use an alarm clock (set the alarm on my watch, more correctly) if I have an early morning flight. Otherwise I wake up whenever I wake up.

Usually it’s pre-dawn but sometimes it’s later.

I wake up like an archetype of a fireman: as soon as my eyes open, I am 100% awake, no coffee needed.

I can go back to sleep if I want to, and that’s also true at any time during the day. I can go to sleep within 5-10 minutes at any point. I am crazily zen-like in control of my sleep process.

My heart rate regularly gets down to around 40 bpm during sleep at 3:00-5:00 am.

I am grateful for my sleep superpower.
