I just want to wish you well tomorrow as you begin your treatments.
I've had plex treatments only once (series of 4) when I had a crisis. I was in the hospital at the time and it was conducted in the dialysis unit. No pain to speak of. For me it was just a little "weird" when I thought about what was happening as I was lying there. If you get cold be sure to ask for a warm blanket to put on you. Make sure you go to the bathroom before going in for the treatment. I remember one time I had to go toward the end of the treatment and it made it worse knowing I couldn't get up and go to the bathroom.
