I still wonder if there can be too much PD treatment for those whose kidneys still function. Last fall after only a few month's of my 4 exchanges I ended up going onto 2 manuals/day and my PD nurse said minimum of 2 hours and that I could get by with dwells of only a few hours max for those 2 exchanges, allowing me to do it at my convenience. I felt great!" i spoke to my Doctor and he told me that I can change back to CAPD and do 3 exchanges vs 4. The reason being is everything you mentioned in your post. Protocol does not work for everyone, I am a slow transporter and doing PD on the cycler with 1.5 bags only are too much for me. I am going to try the manuals, do an adequancy test and see if there are differences. My numbers are great.
