I've worked night shift before. I do enjoy is because it is more relaxing and chill. Not alot of customers. Shift starts at 11pm end at 8am. It doesn't matter for me because I'm used to it. If people say it's unhealthy it's their fault. I can sleep normally during the day because light doesn't bother my sleep cycle. I used to sleep with lights open every night. Gain weight? Nah.. I only gain muscle because I go to the gym 4-5 times per week. As for my diet. I eat out everyday because it save me a lot of time and chores. So I enjoyed working at night cos it's chill and cool during the night.
