Yup, I love my PD cycler and doing it at night. With the addition of Extraneal, I have my days all to myself. Lovely!
I couldn't use extraneal. I used it once or twice, but it dried me out so bad that I had to be hospitalized. Even without it, I didn't need to do an extra run through the day unless I saw fibrin in the bags. Then I would do a run with heparin in it.
Cycler has some advantages over the manual exchange: doing at night and free during the day and less chance for infection. The disadvantage is that residual kidney function may lose faster than the manual exchange.
My residual kidney function didn't start to go until I was about 4 years in, and it took almost another 2 years for it to be gone completely. Even then, I was relying on a scar tissue riddled rejected transplant kidney
