Was officially diagnosed last year, however have had symptoms for many years. Have had a hard time walking any distance along with out of breath. When I got tired of always being the last one and it felt like I was walking in a vat of molasses I decided to see a nureologist. He did the usual exam took blood work. I also have had occular symptoms, ptosis, double vision. So although the blood tests were negative he started me on mestinon 60 mg daily. I thought I had found the cure- felt like normal. Naturally it didn't last. Currently on mestinon 180 once a day. Will be seeing him again as my arms are occasionally getting involved. Think I may need a little more mestinon. Oh, forgot to mention I am 71 yrs old. Female.
