Find me a piece of literature stating you need to drink more than a gallon or 2 a day. Total b.s., it's been proven that people that do moderate exercise need 8 glasses of water a day. The person not running around sweating requires even less. Beyond the 8 glasses of water a day, you should be drinking what you sweat. Now if you really think you're sweating a gallon of water... you must be training for hours inside of a sauna. There are dangers involved with drinking excess water... but don't take my word for it... you guys rely too much on bro science
