If your circadian rhythms are out-of-tune it's going to be tough.
Stick to sprints 1x a week but up the intensity.
You could try IF'ing, but with your schedule it might be tough and make stress worse.
And if you're not taking a magnesium supplement already, start now.
Mahalo to all

+1 on the sprints...maybe add some pullups btw them.
