If I have specific thoughts or concerns swirling around in my head, I find it is sometimes helpful to jump out of bed, find a pen and paper, and write them all down. Often this lets me get to sleep more easily afterwards, as I no longer have to worry about "remembering things for the morning". Getting a period of decent exercise (walking, jogging, etc) between work-time and sleep-time also seemed to help break up the day for me, and ensure I am both somewhat physically tired as well as mentally tired.
