Eat
Make your lunch. Bring in healthy foods like fruits, vegetables, nuts, water, juices, sandwiches, and other favorite foods. There often is nothing good for you to eat at 2 am. No matter where you are, eat a meal before work, and have a snack 3-4 hours before your night shift and then a light meal as your last meal before leaving work. You should wait until, you get home for next meal
