I just don't drink water. Then I don't have to worry about it.
The way I see it, around 80% to 90% of my fluid intake is either coffee or tea (or lately, Snapple Tea+Lemonade which is like the nectar of the damn gods, and only 10 calories. Not a paid person I swear, that shit is just good. Arizona isn't bad either. Anyway...)
That Tea and/or Coffee is itself made up of nearly 90% H20. Very little of it actually bonds with any of the other chamicals - caffeine, sugar, or the coffee/tea itself - so most of what I'm drinking is water already. Why the fuck would I ever want to drink unflavored water, when I can drink coffee and ENJOY it, and then just drink 10% more of it to make up the difference?
To me, this is crazy. I drink a coke maybe once a month. Almost all I drink is coffee and tea, and they are almost entirely water. What the hell do I gain from drinking straight up water???
That said, I make all my coffee with tap water because we live on a river-fed lake and so the water source is about a mile away and constantly moving (i.e. very clean). But we have an office in town (around 30 miles from here) and I swear I could probably light that stuff on fire. It's from an aquifer, but nearly 40% of it is recycled now, so it tastes like over-treated ass.
Needless to say, at the office, I drink coffee for the same reason people drank mead centuries ago - it was considerably less likely to outright kill them than plain water.
But up here? The water is fine, it just seems insane NOT to make coffee or tea with it instead.
