I been trying to reply but I been having computer troubles. I have MG-Myasthenia Gravis since I was 3. It got severe at 18. I had a thymectomy at a young age. It's been a long process. I have dyplopia and ptsois or whatever of both eyes. On various ever changing medicines. It doesn't change alot but you have to take em a long time before you notice if it works or not. Like I said It's been long. I am waiting on three eye surgerys since 2006.. Still waiting. Nothing new! But I am a good candidate for it whenever that time comes.
