Black out curtains are a must, and most people benefit from having a source of masking white noise (like running a standing fan) to help drown out ambient noises. Swing schedules are the absolute worst on your body, so if you're going to be primarily doing things during the night, try to keep a consistent sleep and wake schedule, just as you would during the day. Most people are not going to be super understanding of the fact that their 3PM is your 3AM- your social life might be a little turbulent, and your coworkers might be some of the only people you interact with for awhile. Figuring out meal planning in advance will likely be important, since you're not going to have as many easy options that are open late at night to make impulsive purchases for meals, (though that is dependent on the area you're living in, to some extent.) You'll probably want to get some form of online banking services, but also look into how you can schedule things that are only open during daylight hours- medical appointments, dental appointments, bank appointments, grocery shopping, clothes shopping, etc.
