I'm 23 and i'm going to be working my first night shift, any suggestions on sleep and food and drinks to keep me awake but not energy drinks or coffee?

Will depend on your : sleep/ear cycle since that will determine your energy level needed for your night shift. Get a good 7-8 night sleep during the day using black blinds/eye shields. Then decide whether you need to eat a meal in the middle of your shift versus snacking. Organic protein bar is great to give you stamina. Organic raw nuts, fruit is good. Also, a green smoothie with raw cacao and raw grapseeed flour.
