Dialysis can just be unpleasant if you would crash your BP, the session seems like it is an eternity to finish up if that happens.
If your BP is stable the session is pleasant, it cleans your system which is why I am able to eat much especially now @c0ff33a that I was able to tell the nurses about what I want for my dialysis with an aid of caffeine pills.

I don't mind your experiment about your MARLIANS bot, go ahead Sir.
