Interesting, we use the AK-96 Self Care machine. I'm not sure but I believe once we have set the amount of water to come off we can't change it. We can only turn it off. Which he's reluctant to do.He went in clinic for dialysis Thursday (have to go once every two months) and they want him to start doing it every other day...he's fine as long as his weight stays relatively stable. They've also told him to stop eating while he's on the machine (you think someone could have said something earlier). We'll see how it goes. Thanks for the welcome.
