For the last two weeks I've been drinking over three quarts a day and its done wonders.

Without enough water, we become dehydrated, which reduces blood volume, that in turn means less oxygen is getting to our muscles. Unfortunately our bodies are slow to warn us of dehydration; the saying goes that if you're thirsty you're already dehydrated.
A good rule of thumb is to drink one half ounce of water for every pound of body weight. So while the old eight glasses that we're used to might work for many people, its not enough for the likes of a 200 lb guy like me.
So go ahead, have a glass of good clean water, or two or ten- its refreshing, cheap and really good for you!
