Never underestimate the power of a Mental Health day.  I was feeling very stressed about all aspects of life and so I took a vacation day (Mental Health Day) on Friday.  I slept in, watched TV, and went to see a movie (Sorcerer's Apprentice).  After resting all day, I let the busy weekend begin.  I still feel refreshed.

If you have the time, I heartily reccommend taking a day.
