The sleep of the unjust

We did receive our newspaper. What I didn't get was much sleep. As I've aged, health issues have made doing so increasingly difficult. However, it often feels like my body just refuses to nod off. My eyes can be watering from watching Korean and Japanese reality shows, and I can be yawning regularly, and I'll still lie there for four hours, futilely changing position over and over, until eventually I go under for maybe two hours. Don't suggest anything diet-, exercise-, bed- or whatever else-related. I've tried it all.
