Reality Check (first day back)

I went in to the studio today.  I was around for a little over 4 hours.  Mostly checking in with people, saying hi, writing email etc.  Between the work effort and the viciously hot-and-humid commute, it was too much.  I came home at 5PM and passed out soon after.  Its 9:30PM and I just woke up.  I’m groggy and basically need to go back to bed.
