Good news! GFR now up to 33 (it was 24 in Feb) when neph decreased diuretic and I continued diet and kept using the recipes I posted, neph says both things are responsible for the improvement. Neph also recommended I keep protein below 35 grams daily, which I have done, and BUN and creatinine now are lower. So have moved back into stage three. I took her the next-to-last copy of my cookbook and as soon as she and primary have vetted it and I have made any necessary corrections, I'll post the final copy here so stay tuned!
