I'm sure I don't need to tell you that excessive sleeping is a sign of depression. Does your W always sleep that much?
I know that I work a lot and sometimes spend nearly the whole weekend in bed, but that's not a regular thing. It's maybe a couple of times a year, usually after one of our disaster recovery tests when I've slept maybe two or three hours over a two day period. Once in a while is OK, regularly sleeping that much may indicate a problem.
