Adjusting Your Sleep Schedule
It's difficult to maintain a non-traditional sleep schedule, but many people are able to do it successfully.

First, it's key that you minimize your exposure to morning light when you come off your shift. If possible, wear dark sunglasses when leaving work. Try to minimize light exposure until after you have slept.1

As in all situations, it'll be important to establish a regular sleep schedule and consolidate your sleep periods.

That is, rather than sleeping for a few hours at times scattered throughout the day, try to sleep in one long stretch as you would at night.2 Your body will establish a new circadian rhythm, allowing you to be awake during the night and asleep during the day.
