Water.. lots and lots of water. I'm on a mission to see if I drink enough, all those little holes I poked into my skin (found a weird new use for my fangs) will start to leak. I'm taking bets.
If you start experiencing headache, personality changes, changes in behavior, confusion, irritability, and/or drowsiness, stop the water and eat some crackers or a banana. You can muck up your salt and potassium levels with too much water.
