how much water should i drink yahoo answers
Rating Newest Oldest. Best Answer: i've heard that if you're thirsty, you're already dehydrated, and that you should be drinking regularly throughout the day. it was my understanding that most experts agree that 64 ounces of water a day (that's 8 cups) is what you should drink. know people say drink 6 to 8 glasses of water a day, but I'm a 16 year old female and I try and drink that much, but I need to go to the toilet lots, and that's embarrassing so I tend to not drink much, then I get headaches. Please help me!!
