I work nights and i like it for the most part. the pace is slower, i don't have to deal with a lot of annoying CWs or mgmt (it's only me and one other person at night), and I get paid more. but i think i may have to go back to days. i've been doing nights for about 3 years and i can tell it's taking a toll on my health. I've gained a lot of weight, am constantly sleep-deprived no matter how much sleep i get (daytime sleep just isn't as restorative as nighttime sleep), and it's hard to have a social life. i think it may be worth the hassle and pay cut to not feel sluggish, blah, and run down all the time.
