As I write this, I'm coming off a particularly difficult 9-day-in-a-row work stretch. I've worked as many as 11 days in a row before, but in my former department. My current position is much, much busier and more physically demanding than my other job, and I was woefully unprepared for how utterly exhausting this was going to be for me.
One of my favorite things about working nights and still waking up at a decent (for me) hour is that I can attend to housework, cook brunch, get ready without rushing, and run errands without too much hassle. I can even sit at my computer and relax for a bit!
