Please realize that there are times when the mestinon is of little help. Last year when my MG was rageing the mestinon did little to stop the ptosis and double vision even though I was taking up to 360mg and more. I ended up on prednisone which stabilized the MG but had side affects. There are other treatments for MG and you should consider all of them with your doctor and find out which is best to treat your symptoms. Find a nuero that is experienced with the disease and you trust. There is always the Mayo Clinic or John Hopkins where you know your diagnosis will be well researched.
