I have same problems. The Mestinon helps my droopy eye lid but the double vision was a toughie. I was on Imuran for a year along with Mestinon and IVIG treatments. My double vision clearer up on my second series of IVIG and has stayed pretty good. My Dr took me off IVIG to see if the Imuran was doing any good. Well we decided it wasn't, so now we are switching to Cellcept and Prednisone.
