I've not heard of drinking that much hurting you. The water intoxification deal is usually when someone consumes a massive amount of water in a short period of time. Sometimes downing a lot of water while working out can cause some problem...though I don't remember what it does. Yet drinking it throughout the day...I've never heard of anyone having a problem from it. HOWEVER...it COULD be indicative that you ALREADY have a problem. Most people just don't or can't drink that much. Perhaps you're more thirsty than normal because of some other medical problem and I think THAT is why you need to see a doctor. Diagnose any possible problems early.
For myself, I refill 25 oz. bottles that I keep on hand. I drink 3 to 5 a day, depending. If I'm out in the park for several hours, jogging, etc. and its 85+ degrees, I can usually go through a couple bottles just from that. And then I consume my usual 3 throughout the rest of the day.


I WILL let you know what he has to say, though
