Hello astrobridge (most interesting name!) and welcome to IHD.
I do hope you get very soon answers to your special questions.
My own dialysis-years consisted of having "installed" a tunnelled chest-catheter-dialysis-access, which, with very careful handling (greatest cleanliness, no water near it whatsoever etc.) lasted me for four years without infection etc. (I daresay I was very lucky ...), until my transplant "came along", which, of course, has its own trials and tribulations ...
Unfortunately, I cannot be of any help concerning your Liberty cycler noise etc. But from my own dialysis-experience I know, that a kind and dialysis-friendly diet (in my case vegetarian) plus keeping as fit as is possible, creates, in my opinion, the very best chances.
I wish you the best of luck and please take great care, Kristina.
