Ditto. And I might add that I never get any headaches -- well, maybe one every year or two -- and that my pee is only lightly coloured. You and I are living proof that the notion that you must drink X cups of plain water is complete bunk. As previously noted, many other drinks and foods contain lots of water. As long as you're sufficiently hydrated, it doesn't matter how you get there.
