You sound exactly like me and I am much better if I take cellcept. I took mestinon for 2 years and I totally hate it. It helps. It also causes gut cramps and urinary system cramps.

My voice gets hoarse. My doctor says it is due to fatigue of my muscles that produce the sound.

My legs hurt. My doctor said that it is because the muscles that do work have to work overtime so that I can walk since other muscles malfunction.

When my eyes are tired, my eyelids droop so bad that I can't see out. Before they close totally, my vision is blurred.

I went through a stage of having a really bad memory issue. It is much better now. My neurologist thinks that I was not getting enough oxygen when I slept due to untreated myasthenia gravis.

Another weird symptom that a lot of us seem to have is that my ears will seem all stopped up when I am tired. It drives me crazy.

I also talk like I am drunk. Slurred speech. Weird sounds. People at work have accused me of being a major pot head. I am not.

I suspect that you will figure out that all your issues are from the MG.

Mestinon is only a symptomatic relief. It is somewhat like taking aspirin for the pain from a brain tumor. Sure it helps the symptoms......
Lowering the antibody level does more good though.
