(Also, I feel like this is where Sherlock got Joan wrong. In my head canon, she is a perpetual oversleeper, probably exacerbated by late nights and long shifts during student days, residency, and surgeonhood, and it has less to do with how much she enjoys her work and more to do with the ethos of catching as much sleep as you can when you can.)

Haha, this is the first thing I shouted at Sherlock when I watched the first episode -- SOME PEOPLE JUST LIKE SLEEPING, SHERLOCK! It bothered me before I knew that this Sherlock was going to be presented as so consistently talking out his ass; now it just makes me laugh.
