Bingo! You can most certainly drink too much water and jack up your body's electrolyte balance. I usually drink a liter of water before I even get to work in the morning. I'll drink another liter before workout/lunch and have to urinate probably 4-5 times before my workout. I think I definitely keep myself well hydrated, but I also know there's a limit to how much water I should drink.Actually, you can take in too much water and mess up your body's balance, but most people don't. Best way to stay hydrated is to keep drinking in AM until you pass clear fluid and then back off a bit to keep it clear.
