Suggestions Please

So on the days leading up to night shift (which is 6:45pm to 7:15am), I have been trying to stay up later and later . . . much past my 10pm bedtime which I was used to. Anyway, I am running into a small problem, what to do past 10pm. I don't like watching TV all that much and there are only so many things you can look up on the computer. Any ideas would be most helpful!!
