9 cups of water/liquids is kind of a generalization. it's kind of an average, not exactly what every person should have. kind of like someone who is 5'9, 215 lbs would need more water than someone who is 5'1, 95 lbs. basically to find out how much water you need a day you need to drink enough to where your urine is clear. as long as your urine is clear you have been drinking enough water. unless you take medication that turns your urine strange colors, like some vitamins turn your urine colors. also people who have boring desk jobs such as myself would need less water than someone working an on-your-feet-all-day type of job.
like they said,basically it comes down to just how much you take in.if for some reason,the two don't seem to 'match' like if you are going alot more often than what you would think is the norm or if you are not putting out alot of urine compared to what you take in,those are things that would require evaluation from your doc to see why there isn't that match.Or if you suddenly should feel thirsty all the time,that can indicate underlying metabolic issues.but if you feel you are probably,like that average person,there probably is not any sort of problem.
is there a specific reason that you asked this question or just curious?FB
