@dks And remember, when the medical team talks about fluid intake during a day, they also are considering the vegetables and fruit, or soups and stews you might take in. It is not just actual water/milk/coffee/tea.

Like @collegeprof, I like to use crystallized lemon or orange in my water. Each morning I start the day with a full glass of crushed ice and water, using a straw to sip on it and break the hydration issue from overnight. Taking in small amounts of fluids during the day may help keep you from feeling overwhelming thirst. Start watching your phosphorous in what you choose [no dark colas!] Plain water is great, but face it, we all want some little flavor, right?!

Here is an informative article from the American Kidney Fund. While it speaks about fluid while on dialysis, if you scroll down, it goes into fluid suggestions in different stages. As you can see, it is important to be aware of your own situation, and getting guidance from your medical team is crucial. Being on peritoneal dialysis, I try to stay around 48 ounces a day.

So, drinking 2-3 liters of water daily with 3a is fine as the kidneys can process much more water than that. Overtaxing the kidneys can occur if we dink more than a liter in an hour or less so be aware and be safe. Johnmacc
