when you have to pee every 20 minutes. And it truly feels like you've been in a car for the last 6 hours after drinking a Big Gulp. And when you run to the bathroom you pee for all of 4 seconds. 20 minutes later, lather, rinse, repeat.
We watched a movie Sat night (Battle LA, not horrible for a shoot-em-up alien movie) and I thought DH was going to lose his mind having to pause so often. He's threatening to not take me to see Transformers 3 in the theatre when it opens cause of my pee habits lol.
