Is it wrong that after taking 72 hours of PTO last month, all I want to do with my free time (defn: time when I'm not at work) is sleep and veg out with friends and/or movies? veg out with friends and/or movies and sleep?

Considering how I spent those 72 hours (+6 days of weekends, and lots of other hours), I don't think it's that bad. Just understand that when/if I don't pick up the phone or respond to your email, it's 'cause I'm exhausted.
