MG is the only disease I am aware of that they use mestinon for - and yes, it is possible to have mg without eye or breathing weakness. I was diagnosed in 2000 and had slight eye problems at first but mainly overall weakness. It was 5 years before I started having breathing problems and gradually, my eye problems worsened to the point that I have had double vision for 3 years.

We are different and unique and mg likes to keep reminding us of that!
