I've worked night shift for many years, most of my career, and I wouldn't have it any other way. I work from 2:30 to 11 pm, I wake up whenever, and I generally don't hate nights. I've worked midnight shift (10:30 pm to 7 am) before and it was exhausting at first. after a week, I got used to it. That shift sucked the life out of me because I had kids at the time.
