Another Restless Night

I had another rough night sleeping last night.  Almost identical to the last one.  I was working on the computer and dozed off in the chair.  I moved to the couch and awoke several times before the blare from my alarm alerted me to the start of my new day.  I'm still unsure of the cause.  I know that I am tired and I know my body wants rest.  I just don't know what keeps stopping me from getting the rest I need. We'll see what happens tonight after a day of working both jobs.  If tonight is no better, it may be time to invest in some type of sleeping aid.
