You need 64 ounces of water per day....but you receive water in other forms than liquid!
Some veggies/fruits are nearly all water......
And some other drinks count toward your daily intake of H2O
Sodas (Diet I hope)
The 64 ounce thing is also a misnomer...it depends on your activity level.....a 180 pound man running 3 miles needs more than a 110 receptionist... Hydrate according to what you are doing.
I dont drink enough, and I know it...every morning I have a glass of water and some type of juice...usually have a Monster for Lunch...then one or two glasses of water before I go to bed....My goal this week is to add another glass of water while I am at work....Baby Steps
My tip....Before I leave in the morning, I will put my water in a travel containor (no plastic bottles for me) but I will use mostly ice, that way when I am ready for it...it will still be cold and I am not inconvenienced to walk across the building to the fridge to get my water....
