I second everything Peety said.... yes, by all means, DO prepare yourelf for an accident- they are practically inevitable. Carrying supplies with you, extra pair of pants, underwear, baby wipes, plastic bags- this will ease your mind. And also, everywhere you can use the bathroom, use it! I find too, when I go into a store or business, I immediately look around to locate the bathroom- just knowing where it is is a big relief. And try not to sweat it too muc- the more you think about
it, the more you'll feel like you need to use the bathroom. It's tough.
