There was a feature on the radio about the modern office obsession with drinking gallons of water - the doctor they had on that day said you can drink loads of water if you like, it won't do you any harm unless you take it to extremes. But it won't do much either, other than make you wee and sweat more. Apparently you'll know when you need more water, you'll be thirsty. But if you reckon it's working, it's a cheap placebo if nowt else.
It's good to keep hydrated but 3 litres a day is a bit of a nonsense.
