Yes, the science has moved to "drink when you're thirsty" a long time ago and it's annoying how many people believe drinking 3 liters of water per day is a key tenant of human health.

(most of) Our bodies are quite good at telling us when we should drink more water. You should never be forcing yourself to drink

All that being said, I'm not sure GP was necessarily endorsing the idea that you should drink a certain amount of water a day. I read it as a suggestion to pull away from the screen and listen to your body

But why? unless it’s a copious amount of water like a gallon or more in an hour or two or something insane like that what is the problem with drinking water? I would assume it would just have positive effects.

> "You can become dehydrated if you take in too little. And you can actually cause problems, such as exercise-induced low sodium or hyponatremia, if you take in too much," says Dr. Sara Filmalter, a Mayo Clinic family physician. "So the general rule of thumb at this point among physicians is to drink to thirst."

		I've often read (sorry, no citations handy) that by the time you notice / feel thirst, you've already been dehydrated for some time. And chronic (mild) dehydration is much more common than hyponatremia. I'll always err on the side of drinking water whenever it occurs to me (and deliberately starting my morning with 16-20oz on waking) instead of waiting to feel thirsty.
