Mestinon works for me but ONLY in conjunction with regular PLEX Treatment. IVIG almost killed me as it caused a pulmonary embolism event in a person with life history of anemia and blood NOT clotting problems. It also put me in a wheelchair, but perhaps you'll have waaaaay better results as SO VERY MANY others who obviously weren't me. BTW, I've been the anomaly most if not all of my life, and that may have tainted my results. Be blessed, and stay strong.
