>without an alarm I can sleep 12 hours.

This was the case for me until I started (a) going to bed shortly after dark and (b) leaving the blinds open.

An really incredible thing happened: I started feeling tired around dusk, and awake at dawn.

Note that it's best to avoid/limit screens and LED lights past dark.
