I'm going to a concert soon and will be out for well over 12 hours with no quick access to a loo. It's a standing only rock concert lol and I don't want to lose my speck if i get a good one. Will not drinking anything be a good prevention?
In my experience it's a good way to get a bladder infection. And faint from standing in a hot place for hours without drinking anything. Couldn't any of your concert-mates save you a place when you have to "go"?
