Resist the urge to hydrate yourself by avoiding the $6 bottled water and continuously drinking and refilling a Dixie Cup with water from the bathroom sink. It's a good way to catch a cold. It never occured to me that peoples' hands touch the tops of faucets. Not until I got home and realized my bathroom sink water tasted like toothpaste. I'm lucky I was only stuck with a cold, and not gonorrhea.
