Vacation constipation; why does it happen?
You go on vacation and, for some reason, you’re unable to poop. You could go a few days or the whole trip without defecating (even after eating a bunch of food!). And, as soon as you get home, you scurry to grab the New York Times crossword, and then make your way to the porcelain throne to do the deed.
