wiscorner, any bodily changes can effect MG. Too much potassium can make MG worse. Did they tell you to stop the potassium once the GI upset stopped? If not, you may have too much of it.

Are you sure it was the flu? Usually people vomit with the stomach flu. Are you on Mestinon?

You were doing pretty poorly when you last posted. Did you recover?

I'm concerned that something else might be going on. Please see your primary care doctor for a follow up visit, and let your neuro know what transpired.
