Drink as much as you want boy.
At least a Litre (Of water)
Well, not really but your life span could be shorter as beer doesn't contain much water, so it's best to have just a cup of water everyday even if you don't have your supposed amount.

I would say drink about as much as you fell is needed.
There is a popular belief you have to drink a certain amount of water. That is not true, you should drink when you feel like it.
Ideally, humans are supposed to drink at least 2 liters of water a day
we shoud drink atleast 5-7 ltrs everyday.
Adults are supposed to have 4 pints of water (four big glasses) and children are supposed to have 2 pints of water daily. If that's what you mean.
You should drink enough water in order to stay hydrated so you will not faint or face any discomforts. I suggest you to drink atleast 1 gallon of water per day.
It is a bad idea to fixate on how much a person should drink everyday. Most people don't even know drinking an excessive amount of water can be fatal. Use your common sense to assess what your body actually needs.
everyone is expected to have 8 glasses of water everyday
