I slept 12 hours last night.  I took a vicodin around 9 - the pain of just sitting and reading.  I can't really go for a walk at night because I'm not sure it is safe.  I need a way to exercise at night = something that doesn't make me hurt.  The ellyptical machine at the gym gets my heart rate up and removes the creakiness of idle time.  But I need something at night too.
