Yes. it is 64 ozs. MINIMUM.. When you exercise, you should drink another 8 ozs, every 15-20 minutes of exercise. So I drink 10-12 glasses of pure water. Any other fluids you get will be from foods you eat. Of course, tea, and coffee count too, but caffeine has a diuretic effect, so you would need to drink more. Don't look at hydration as a chore. Just drink a little every 15 minutes or so, and if you get thirsty, drink more. As you get rid of other drinks, and drink only water, you will find that you crave water. I have to have mine cold, so I freeze them, and drink them as they melt. This tends to have me drinking water at a steady pace, which is what you want.
Eventually you will find that you drink 10-12 glasses of water normally. We don't do this now because of all the bad things we drink instead, like pop, juice, diet pop, shakes, smoothies, coffee, and tea ( with sugar ). So water, with no sugar tastes bad. Switch to just water, and in 3-4 weeks, you will drink it without even thinking about it. Water is our natural source of hydration. The rest are just substitutes.
