Jess you should see if there is a Nocturnal dialysis program in your area. In stead of trying to take off 6 kilos in 3 hours they take it off slower at 8 hours while you sleep. No puf here. They clean and take off fluid for 8 hours . Longer slower dialysis. You will feel so much better. If more dialysis is better then I don't agree with a puf. I do agree with an extra session of regular dialysis. Why waste the money if you have to setup the same.
