I'm never more than two feet from my trusty canteen. If I'm focused on something, muscle memory takes over and I drain it in half an hour. The downside, if you can call it that, is when you're at a restaurant or out drinking you feel like you need six times as much water as everyone else. And I get annoyed on the rare occasions when I get stuck without water access, because I don't feel right and I know how easy it would be to feel right, if I just had a water fountain.

Doubling the amount of water you drink is the single easiest way to instantly improve your health and it's pretty crazy that more doctors/etc don't emphasize it. I'm sure you've done this, but if you google the recommended water intake it'll blow your mind. Over three quarts, and that's baseline male without factoring in any strenuous exercise. I get 4+ every day -- but I know people who have probably never reached that mark in their entire lives. It's impossible to explain to them how they'll feel if they just try it once.

Oh and that problem of just not being able to stand drinking another pint of water, needing flavoring, whatever, goes away fast.
