I have an article on drinking ample water each day -
http://www.bellaonline.com/articles/art11549.asp Drinking juice is NOT a good idea. Juice is in essence sugar water with flavors. Usually the vitamins and fibers of the vegetable fruit are long gone. It's much healthier (except in a very few cases) to eat the raw fruits. Juice tends to givs you a lot of sugar.
Caffeine / coffee is equally bad for you. I wrote about that here -
http://www.bellaonline.com/articles/art16562.asp Caffeine is a diuretic meaning it causes you to pee the water right back out. So it negates the benefits of the water.
Most adults are sensitive to lactose in milk, so drinking that as a substitute for water is also not a good idea. Really and truly, you need to be drinking WATER in order to get adequate water into you. That's what nature intended for you to do <img src="/images/graemlins/smile.gif" alt="" />
