Running through my stuffed head

I'm still sick and the usual side effects of cold medication, for me at least, are a sense of general morose sadness and insomnia.  Quite the combination to try and cheer one's self through when beaten down with a viral infection.  So the last few nights at 2,3, and 4:00 a.m.,  awake in my dark room my mind can't help turning to this tune.
