I have a pretty high metabolism as well and don't drink nearly that much water. It was just a thought that maybe your body isn't processing it right and thats way you have to drink so much. Your obviously not drinking enough water to do this, but it is in fact possible to drink so much water that it poisons your body and kills you.
