Take your pet for a walk.
Personally I find biphasic sleep pretty normal and easy to do when I’m working a job in a timezone that’s behind mine by a few hours.
Go to bed at 12:30, sleep 4.5 hrs til 5:00, wake up with the cat at dawn, take them outside and enjoy the morning tranquility for a bit, go back to bed at 6, sleep til 9, get up to start my job at 10 or 11.
I don’t do it when I have to be up early though, I both always struggle to go to bed early, and I find waking up and being up in the middle middle of the night, to feel more stressful than doing it at dawn.
You also have to remember to have that adapter with you
