I drink at least a cup of coffee when I wake up and carry around a gallon of water during the day and try to drink it all. I don't know what the scientific standpoint on drinking a gallon of water, or the difference in water intake for each individual. All I know is, when I drink a gallon of water...I feel gooood.
and I figure it's good for me. Our bodies are made up of mostly water. I drink coke (even diet) I feel bloated and my skin looks crazy. I drink a lot of water, my skin looks good and no bloat!
