Sleepy

I can hold my eyes open for about half a second before the lids become too heavy and they slowly close.   The darkness lengthens.  It's not for my benefit that I'm not sleeping yet.  As I look around at the room and take a quick inventory I hold of the inevitable for a few moments longer.  Something pops into my head I'm wide awake, just like that.  From only a memory I'm not tired any more.  Well it feels like that, truthfully I'm even more tired when the memory fades because of the effort it took to push it away.  I yawn one more time and think I'll never fall asleep.........
