Jim, I think you just answered your own question! I'm sorry you were in a crisis. You know that it can take a long time to recover from one and getting back to a stable MG place is key.
I frankly wouldn't want a drug that slows my brain activity or could make me stop breathing at night!

MGers have a problem in that some of us don't do much physical activity during the day. It's physical activity that makes our brain know that we're awake and doing enough to make it sleep at night. Physical activity releases endorphins and natural oxytocin.
Have you seen an endocrinologist? Maybe your pituitary isn't working properly. Some people do get small tumors on it.
I think it's important, Jim, to talk to an internist about this. They can look at your overall health, any drugs, and make more suggestions. There can be many causes of insomnia, such as diet even.
Did you know that amino acids, like those in legumes, can make you sleepy once they hit the lower GI tract and are absorbed? So timing of eating certain foods can be useful, too.
Please don't become a drug statistic! Those drugs with the suffix "pam" don't really get along well with MG.
I've had four exacerbations this spring/summer. I have to pamper myself just to be "ok." Please be careful in the hot weather months, everyone!!! A crisis really sucks.
Take it easy, Jim!!!
