I’ve worked nights for a year now 10:30-07:00, sometimes 06:30-07:00 sometimes 10:30-11:00. Most days I sleep at around 10am-noon and get up around 6pm-8pm. What I have noticed help the most is the quality of sleep. Make your room as dark as possible, limit the disturbances to as few as possible even take melatonin if you know you will get 8 hours of sleep and have a couple hours to wake up. I personally have caffeine on the way to work but it may be a good idea for you to wait until your first break. Limit sugar consumption as it will make you crash. The hardest hour is 03:00-04:00 try to have lunch close before this to get more energy and you’ll push through the hour and the 05:00-06:30 will come before you know it
