Why 4 Bottles of Water Each Day?

Several websites will advise you to follow the "8 x 8" rule. This means to drink 8 eight-ounce glasses of water each day.

A typical water bottle contains 16.9 fluid ounces of water. Four bottles of water is equal to 67.6 fluid ounces and 8 eight-ounce glasses of water is equal to 64 fluid ounces.

I just figure that the easiest way to measure what I am drinking is to use a water bottle that I can just refill and mark throughout the day to keep track of how much water I am drinking.

Although drinking water is super important, it is also super important not to drink too much water, so be careful!
