I am on PD. I am connected to a Fresenius cycler. If I sleep through a cycle the machine only drains 3/4 of the fluid it put in (2000ml). To get a full drain plus ultrafiltration I must sit up. A second problem is the rate at which I drain. Sometimes I drain fast, 5 min / 500ml, other times I drain much slower, (12 min / 500ml). All of this results in poor sleep. The drained fluids are clear. Any help?
