kelli: You really shouldn't worry about drinking TOOOO much water. I highly doubt that you are looking into how to drown yourself. I drink 1/2 my weight in water (this week I have sucked at it) which is 92oz per day. I usually drink over that - a lot of days I get to a whole gallon, but that is certainly not a bad thing. Water is very good for you. In fact, I am attributing my not getting sick since I started all this in August to drinking so much water. I really think that is the main reason.
So, just don't try & drown yourself & you should be good to go.
