Good thought which I try to follow when spending my time near a bathroom. Unfortunaately, as a mother of two I want to be near a bathroom if I drink a lot of water. Is it possible that one problem with my GFR reading is that I have just gotten up after avoiding water all night, and not drinking much before I head to the doctor’s office, since I don’t know if I will be called from the waiting room while I am gone to the ladies room at the medical building.
Well, I am not suggesting going overboard with your water consumption, just increase it slightly and see what it does, and then take it from there.
