Two gallons of water a day is a LOT of water. If you use the now-debunked figure of eight 8-oz glasses of water a day, that's only 64 ounces. Two gallons is 256 ounces!

Too much water--it can dilute your blood and make you sick and even die.

Maybe it only seems like you're drinking that much. Maybe you can try using a water bottle with measurements on it and measure how much you drink on a typical day.

That said, if you don't mind water, don't go to diet drinks--go with tea. There are lots of teas on the market, but most of them have high fructose corn syrup as a sweetener, which isn't good for me. I drink plain unsweet iced tea, except in the morning, when I drink hot Earl Gray with sugar and milk. Sugar is not the enemy--TOO MUCH sugar is.

When I am feeling particularly bored with tea, I have a soda--not a diet soda, and I try to find one with sugar (like Jones Soda) and not HFCS. No harm in an occasional soda. For me, occasional means once a month or less, I think.
