They used to say you need about 8 a day...I recently heard 10-12 a day is better. I usually drink A LOT of water... like 16-22 (8 oz) cups a day... then there are days where I don't remember to drink enough, like today... today I've probably only had 4 or 5 cups of water and I'm thirsty...*goes to get water*
I drink enough water to keep me from getting dehydrated. I usually have about 4 cups of either tea / coffee per day & a few of just water in between sometimes
I don't have a rough estimate but I do drink a decent amount of about a litre every drinking and I do drink often.
as much as possible. I have a huge glass of ice water right now, and it is the best thing I have had all day. Can't get enough.
ever since i had kidney stone problems i started trying to drink 2 liters a day. thats tough to do when i dont have work. i usually drink other stuff when im home.
