@BeginningBridge my DH's eGFR took over a year to drop from 9 to 4, which is when he started dialysis, though I think everyone is different in terms of their levels when they start so best be prepared.
He did manual PD at home for a couple of months during which time his creatinine levels dropped from 1100 to 700 – still high but a marked improvement.
He did 4 exchanges a day and found the process relatively straightforward, each exchange took about 40 minutes including set-up, drain and fill. The main restriction I guess is a lifestyle one – doing exchanges at lunchtime and teatime does somewhat limit the amount you can get out and work out of the house/eat out/socialise etc. But he says not to be scared of the process, you can lie down or sit according to preference, it becomes routine and you can just watch telly, or read or whatever you enjoy doing while the PD does its thing.
The firm that supplied all his fluids and drains and everything were wonderfully efficient, very friendly and helpful and took all the stress out of ensuring he had what he needed. Although you do need a fair amount of storage space for it all!
