In your situation, PD might be better, particularly CCPD, done at night while you sleep. With CAPD, it might be a little more difficult for you as far as work goes, since you have to hook up for about 30min, four or five times a day, unless you could carry your PD bags on the locomotive with you and be hooked up right there in the cab (I don't think BNSF would like that too much, though). As for feeling better, once I got used to feeling "full", I felt just as good, if not better than I did when on NxStage. There is the added bonus of not having to deal with needles or blood. If you wanted to stay with home hemo, NxStage is currently working on getting FDA authorization for nocturnal dialysis-NxSage while you sleep. Either that, or nocturnal PD would be the most ideal for your situation. I did just have a strange mental image of wiring a NxStage machine into the cab of a locomotive. Just make sure you're with a conductor who's not squeamish around blood
