Water addict chugs gallons, pees 40 times per day

As far as addictions go, drinking loads of water sounds pretty harmless... unless you're drinking nearly seven gallons a day, like Sasha Kennedy. Her habit has wreaked havoc with the 26-year-old Brit's lifestyle: She lugs bottles of water everywhere, quit a job over sub-par H2O and dashes to the toilet 40 times a day. She rarely sleeps for more than 75 minutes at a stretch before her bladder beckons. But there's no medical explanation for her crazy thirst, which started when she was two. "I only start feeling ill if I don't drink," says Kennedy. "My mouth gets really dry." Still, water beats a Coca-Cola addiction -- another Brit was recently hospitalized for her 24-cans-a-day habit. Yikes!
