Hi Sabrina,
Welcome to the NeuroTalk Support Groups.

There is a forum here for
Myasthenia Gravis

You may want to repost over on the MG Forum as I'm sure the members there will be able to offer you information and support. I'm very sorry that your husband is having such a difficult time and I hope that with correct treatment he'll improve greatly.

You could also use the forum search feature to find other posts using specific keywords e.g. diplopia or ptosis or mestinon

take care.
