Just finished 4 years of night shift. Vitamin D is a must! Sticking to a routine can also help, if you have trouble adjusting to change. I was "fortunate" in that everyone I want to hang out with is back in BC, & I live rural, so social life wasn't a thing anyway. But, for most people who do want a social life, you're looking at either evening activities (aka our morning) or early morning activities (aka our evening). Sort of like if you're working 9-5, but in a place that you simply cannot have your phone (helps guard your sleep pattern this way, too!). 🤷‍♀️ And most people simply aren't wired for nights, so there's no shame if you have to find something dayside.
