If you are awake at 4 am, and have to be at work at 7, should you even try to get back to sleep or should you try to do something with your time?

Check out the phases of the sleep cycle. IIRC a full cycle is around 90 mins so in those 3 hours you can potentially hit 2 cycles and not feel groggy.
With all the benefits of sleep (and the problems from lack of sleep) it would be better to sleep
