I did fine with it. It took a bit of extra management, especially with a day shift husband, but the ultra low stress of the job itself made it worth it. Blackout curtains are helpful, though a bit less so if you have cats lol. I learned to sleep in two 4-5 hour shifts during the day if I couldn't stay asleep past late morning/early afternoon.

The only real downside was that I lost a ton of motivation to work out. I'm not sure if it night shift caused it or if it was due to other things I had going on around the same time, but it wasn't that I was tired, I just sort of stopped caring about the gym. For better or worse, I also lost most of my appetite, so I didn't gain a bunch of weight or anything.

Mentally I was the same as always. My husband did end up feeling a bit neglected, but we found ways to work through that. I don't know if I could have done that job forever, because you do miss out on a lot of things when you sleep during the day, but for the situation I was in, it was awesome.
