How do you get back to sleep?

I'm of an age now where I have to get up at least once in the night, usually around 4am, to visit the bathroom. However, I have real trouble getting back to sleep after. It's a good 3 hours of sleep I'm missing out on. My eyes are already tired and the day is only just begun. What can I do?
