Yes, my Neph never talks about diet. I asked him about drinking water through the night, no opinion. I like to drink sips of water during the night, maybe I feel like it's keeping me hydrated. Sadly, I learn very little from my Neph. Your husband's creatinine seems high. Mine is 1.9 and I'm considered 4th stage. Difference between males and females? Weight? Age? I'm so looking forward to my appointment at Mayo. Although, I might get bad news. Yet to be seen.
