I found job to be an easy part - eventually, everyone got used to not expect to see me in the office before 10 AM. When I switched to remote work for a team in a different timezone, it got even easier (occasional flying in to the office get tricky, though).

It's the family bit that's hell, with a partner who lives on almost a perfect 06:00 - 22:00 schedule and can adjust that to waking earlier if needed, and now kids who also don't like to sleep past 07:00. I'm now stuck in a limbo of family forcing me to get up early, and all my body and mind and soul making me stay up late. A tug of war that's been going on for years now.
