You know that rule “shut down all screens” 1 hour before sleep, but there’s always something to watch/to program etc. Have you found the discipline to do it regularly?
How do you deal with the going-out in the evening, if you strive to wake up at that time?
Do you have some interesting/intense routine like running, which was quite common in american movies?
If i really need to wake up early I chug a couple liters of water right before bed.
To fall asleep quicker I listen to an audiobook with sleep timer and the lights out.
