The best I can do is TAKE IT EASY. If you aren't happy with your neuro, find another. Regardless of their degree most don't know much about MG. You need to find you an expert, Meanwhile LISTEN to your body. If it says you need to rest then REST. Keep in mind we are all different. Heat and stress bother me the most. As for the meds, yes most are bad but it comes down to a matter of what quality of life you want.
