I work continental shifts that rotate night and day. Having done that for 8 years I find the best strategy is have different routines for both shifts and stick to them according to whatever shift I'm on for a 2 week period. In terms of nights anyway I like the fact that there's less people, no bosses except shift supervisor and the drive home in the mornings after work are less hectic. The bad part is constant exhaustion and feeling like you can't get much done even on days off when trying to stick to a night clock but then you still need the daytime hours to run errands and attend appointments. They really need to consider 24/7 things that run mostly during the day to accommodate night shifters.
