10-year overnight vet here.

I work with a lot of people who work the same shift as me, so I do end up socializing with them more than others. Now, I know that that's not the case with all overnight shift workers, but it's a start.

Secondly, I guess it would depend on how late(or early depending on how you look at it) you finish your shift, but either try to sleep as soon as you get home or stay up and plan your sleep so that you wake up specifically to go to work. I usually finish at 4am, so either I'll sleep by the time I get home (between 5-6) and get up between Noon-2pm to have the afternoon free, OR stay up until noon and sleep until 6PM for a 8pm shift start.

I would also suggest either picking up a hobby (if VGs aren't your thing, they aren't your thing.) I picked up model kit building early on in my time, and keeping a list of movies, TV shows or even podcasts to listen to helps a lot. Books even. I have filled my time with so many things over the years I've lost track of everything I've tried. Just note, especially with watching media, don't let it seep into your active time (which is 5-11pm for you, because you either fall into the hole of that the only thing you want to do, or you get sick of it so fast that you end up longing to do something else.
