8 Glasses of water!!

I count anything that DOESN"T have caffeine, since caffeine is a diuretic and can actually lead to dehydration. So herb tea, yes; black tea, coffee, or diet soda--no.

The whole 8 glasses a day thing is a myth. As long as you get enough fluids to make your urine a pale yellow you're getting plenty of fluids in. There is no advantage to chugging water as far as weight loss goes and you can actually drink too much and rob your body of essential minerals that it needs. Drink whatever you feel like drinking and enjoy your life instead of spending it in the bathroom.

I drink way more than 8 glasses. This gets asked all the time on here and always turns into a ridiculously long thread.

Personally I do not count anything that isn't 100% Pure unadulterated Water but that's just my way of doing it.

I agree with the poster that says as long as your pee is pale yellow you are hydrated. I have a sports bottle that I fill up and keep with me all the time which is how I get to drink so much water and I don't drink coffee.

Heh. Where do you get your pure water?
Don't say from the tap, or bottled water, or even Brita filtered, because those aren't pure water. they're full of ions and minerals and gasp, chemicals...
Are you distilling your water?

Water samples were collected from 384 waterworks that supply 70.9% of the Norwegian population. The samples were collected after water treatment and were analysed for 30 constituents. Although most constituents show wide concentration ranges, Norwegian drinking water is generally soft. The median values obtained are: 0.88 mg Si l-1, 0.06 mg Al l-1, 47 micrograms Fe l-1, 0.69 mg Mg l-1, 2.9 mg Ca l-1, 3.8 mg Na l-1, 6 micrograms Mn l-1, 12 micrograms Cu l-1, 14 micrograms Zn l-1, 9 micrograms Ba l-1, 15 micrograms Sr l-1, 0.14 mg K l-1, 58 micrograms F- l-1, 6.4 mg Cl- l-1, 11 micrograms Br- l-1, 0.46 mg NO3- l-1, 5.3 mg SO4(2-) l-1, 2.4 mg TOC l-1, 6.8 (pH), 5) microseconds cm-1 (conductivity) and 11 mg Pt l-1 (colour). Titanium, Pb, Ni, Co, V, Mo, Cd, Be and Li were seldom or never quantified, due to insufficient sensitivity of the ICP (inductively coupled plasma) method. Norwegian quality criteria, which exist for 17 of the constituents examined, are generally fulfilled, indicating that the chemical quality of drinking water, by and large, is good in Norway. For Fe, Ca, Mn, Cu, pH, TOC and colour, however, the norms for good drinking water are exceeded in more than 9% of the samples, reflecting two of the major problems associated with Norwegian drinking water supplies: (i) many water sources contain high concentrations of humic substances; (ii) in large parts of the country, the waters are soft and acidic, and therefore corrosive towards pipes, plumbing and other installations. Most constituents show marked regional distribution patterns, which are discussed in the light of different mechanisms contributing to the chemical composition of drinking water, namely: chemical weathering of mineral matter; atmospheric supply of salt particles from the sea; anthropogenic pollution (including acid precipitation); corrosion of water pipes and plumbing; water treatment; decomposition of organic matter; and hydrological differences.

Not sure if you are being pedantic or not? I mean water with nothing added, no kool Aid, teas, coffees.

FYI, I actually have a Reverse Osmosis (RO) Water Filter System so I guess my tap water is pretty pure in that respect.
