No, you aren't alone. If feels just like the day after the last final exam. Sort of a letdown after all that work. Where's the parade? Hubby and I go to a special vacation spot every year after tax season. Takes me about three days before I'm really in the vacationy, beachy, boozy, (dare I say sexy) swing of the whole thing. I think it's important to take a vacation after working so hard. If I just stay at home and try to relax, I feel the same dejection and emptiness you seem to be describing. Have an adventure!
