Good question!

Have you discussed with neuro or gastroenterologist?

Important to figure this out with your medical team so you have no issues with weakness. My understanding is they use some drugs for the 'twight anesthesia' that can make MG patients weaker. So no Mestinon and 'twilight sleep' could put you at risk if your medical (esp anesthesia) guys are not aware of your MG status at time of surgery.
