@mister kitten,
Tea and water. The tea makes up for the fact that water is relatively cheap. But with that being said, I have never actually taken a sip of tap water from a sink or a drinking fountain probably in about 10-15 years. Why? Hilariously, when you drink your cities water, you are drinking everyone that waters ever been with! LOL! Seriously though, the amount of chemicals in tap water is amazing. I can understand fluoride for young people since it is a public health concern, but many cities have such diverse residuals as; birth control, caffeine, acetaminophen from the Tylenol we take, nicotine, and even cough medicine. And this is not even counting the relatively high amounts of chlorine in water. I read this article on BBCnews of all places that linked urinary tract cancer to heavy chlorination in Louisiana (specifically new Orleans because of its vicinity to the Mississippi, lake ponchartrain, and the gulf of mexico). Light salination I think is alright up to a certain point, softeners (which contain known carcinogens) are very bad for you and the water tastes disgusting. If you have ever been to New York (or a Hampton Inn for that matter because they use those systems) and you notice the water has a velvety feel to it, that residue is the chemicals used. To get a nice little scare, look up your areas water quality;
