My husband is at end stage. If you have any % of kidney disease I cannot stress enough how much you need to alter your diet and lifestyle. I have for him and to preserve my health so I can care for him. Get both Lees books. Read and adhere to them. Dialysis is hell. Prevent it as long as you can. Drs didn’t give us the information we needed to help him, patched him up and sent him home for me to care for. This book is the most valuable information I have found thus far. Thank you to the author for sharing his education with us.
