My husband and I have a joke that my bladder must shrink up to nothing the moment I get on an airplane.
On any normal day, I can go for hours without having to use the bathroom, but the moment a plane takes off - even though I used the ladies room in the airport - I need to visit the lav and have to continously all through the flight. Usually about every hour to hour and a half.
The most embarrassing is when I come back from from a trip to the lav, sit in my seat and have to go again 30 seconds later. I hate that!
Yes, I always request an aisle seat!
BTW...Men, you're not at home. Please, put the seat down when you're finished!
