Drinking too much soda gives you a kidney stone

2-3 quarts a day, unless it's really warm out.

As a distance runner I tell people hydration should be constant. If you wait until your thirsty...it is too late.

Water for me,gave up soda years ago,but would like to give a very late thank you to those elementary school kids that sent us Kool Aid packages in good old RVN was the only thing that could cut the taste of the water purification tabs.
