Sports Drinks alternative?

[Helen]

Is there a sports drink alternative out there that isn't all sugar? I drank Gatorade this weekend instead of water and got a real gut-ache from all the sugar. Can you get a mix that's just electrolytes and other good stuff?

I think that normal mineral water is the best drink of all. You get all you need from this drink and you avoid all those Es that are usually included with all the commercial drinks.
