I sort of did this by accident over the last year or so and I tend to wake up every morning by 5 or 6.

Always been a night owl who never went to sleep prior to midnight before that.

That's impressive! Shifting from a night owl to waking up at 5 or 6 is a huge change. Definitely motivates me to stick with the gradual bedtime adjustment

It was definitely not natural for me, but I have done it.

That's inspiring to hear. If you can make the switch, I’m hopeful I can too with some consistency.
