@johnmacc I am not sure if there is a "standard" for the amount of water to consume daily. We all differ in size, weight, gender, and ckd disease stage, but your nephrologist can give you a definitive answer. The Internet consistently says three liters daily, but that may be a problem for some.

You are so spot on when you say consuming too much water in a short period of time can cause taxing episodes to the kidneys. Some of us at times have a tendency to do that.
