I'm still doing a weekly plasmaphereseis every Wednesday it's going to be my 73rd...on the 6th day I'm starting to have difficulty speaking very slurry and numbness in face, lips and tongue and my taste buds get affected, my food doesn't taste the same, a few hours after my exchange I'm already starting to feel better and after a good nights sleep I'm back on top of things...at one time I was doing back to back Plasma exchange and IVIG and wasn't really worth it, it took 7 hours so I only do Plasma exchange and works wonders for me so far and I'm very lucky to be able to use my arms veins...
