Blackout curtains, melatonin, whatever you can to control your sleep and block out noise and light are a must. The ice cream man can be your enemy. Stock up on emergency 5 hour energies, I like to have soylent in reserve too because sometimes food and shit won't be available.

I won't lie, night shift strained many of my relationships. It took quite a bit from me. But it can give back too. Things like audiobooks and videogames replaced drinking at bars with friends. Have solo hobbies prepared.

There's a temptation to become diurnal on weekends that will work against you.

Also, you have to be firm about your schedule with people. They don't consider night shifts in their plans, so you want to make sure you let people know often what can or can't work with your sleep cycle.
