Been there, done that, have the tee shirt and the underware. No big deal. Just think "happy thoughts", like blue skies, puffy little white clouds, all engines still running smoothly. If you're lucky, a couple of cute young nurses will hold your hand. Next day, go to your favorite pub and consume vast quantities of youir favorite brewed beverage. You need to flush the magnificient beast out. You will dance around a bit (Michael Flatley isn't the only guy who can do the riverdance.) But if you get stupid enough, you won't notice it. Good luck and pee straight.
