I read (maybe here) that one should drink an ounce of water for every two pounds of body weight.

Someone said that it's too much, you'll flush out all of the vitamins in your body, so take a multi every day; and don't forget, there's also water in food.

Q.: How much water is too much?

I'd say the best thing to do is just remain hydrated throughout the day, have some water every 1-3 hours (depending on how hot it is, and whether or not you're out in the sun and how active you're being, if doing intense activity, frequent (15-30 minutes) sips would be the best choice). That's my 2 cents.

The RDA of 8 glasses of water is too much for most people just so you know.

The rule of thumb that I use is 1 litre/1000 calories expended. That takes into account activity level and not size and it closely matches water output. Of course in hot climates you sweat more and you need more water.

here's an article on water intoxication which is what happens if you drink too much water:

Also look up "hyponatremia"

Caffeine and alcohol are diuretics so they should not be counted fully as part of your water input. They can keep you hydrated though.

To answer your direct question, it does flush sodium out of your system so you may need to supplement to keep your electrolytes in balance. I don't think vitamins are an issue.

Try to match your input to your output. Your body will adjust retention and absorption to achieve balance. A good rule of thumb is that you should urinate 4 times a day and your urine should be light yellow.

thats a very hard thing to acheive as stated in the article:
I wouldn't worry about potential death from it. Just go alongw/ their guidlines or just by what your body is telling you and you should be ok
