I am retired and living 100% on my circadian rhythm. There is still not enough time left in the day to do all the things on my to-do list and by the time I go to sleep I am too tired to meditate or do anything else. If I ride Zwift in the evenings it helps me even more. It wasn't always that way as I worked all kinds of odd hours over the years.
All I can say is: Stay on your feet all day, take those shoes off, put the feet up and if you go "ahhhhh", you'll be asleep within minutes.
