The water cure can't hurt. I have known one of these "water people" like you who are so obsessed with water that it almost becomes comical. Whatever you say, the solution is "drink water."
I wouldn't say I'm obsessed with it. In fact, I get away from it fairly regularly. All I know is that I tried it and my lower back improved a lot, and pretty quicly too. I've only made one visit to the chiropractor in about two years now. Unfortunately, when I was growing up, I drank almost nothing but Pepsi. So I'm sure that I damaged my health with that (probably took fifteen years off my life). Reason was that I absolutely HATED the taste of tap water. When visiting my great grandmother in Hungary as a child (I was about 10), I drank incredible amounts of her well water every day and just kept raving about how delicious it was.
If you actually look at what's in most municipal tap water now, it's filth--from chlorine (poison) to fluoride (poison--which also has the effect of making people passive) to birth control pill residue to prozac (the latter stuff coming from people's urine), etc. We use a reverse osmosis machine at home, and when our nephews and nieces come over (they don't purify their water despite my having told their parents about it), they also can't get enough of our water.
You could be like Stephen Hawking and they'd come up to you and say "You're not drinking enough water."
That's hilarious.
But water is too boring to drink "straight" so I use it for tea. I'm a big, big tea-drinker. You could probably ameliorate the blandness of the water-cure that way.
I like purified water, but get almost sick from the taste of tap. You get used to tap water over years, but once you try RO purified water, and then go back to have a drink of tap, it turns your stomach. If we go to a restaurant and get water, my kids take a sip, immediately grimace, and complain that it's "tap water".
