heigh-ho, heigh-ho, back to work I go

Yup, that sums it all up.  I returned to work today after almost 2 months off.  I. am. exhausted.  Plain and simple, that's all there is to it.  I will be putting on my jammies and crawling into bed in the next half hour.  If I fall asleep, I fall asleep, but the tv will be on.  Put a fork in me, I'm done.
