Re: How much water should you drink in a day?
I don't think it makes a huge difference of when you drink it, but you are probably a bit better off not drinking it all at once. I try to get most of my drinking (for my transplant) done before dinner, so I don't have to run to the bathroom at night.
As for keeping your creatinine stable, there are lots of things. Hydrating will help as will eating less animal protein, keeping sodium intake down, and making sure that your blood pressure is in a normal range too.
