That has to be frightening, not knowing when they are going to happen. I briefly looked at that site that Yzen posted a link to the other morning. It looks like it has some really good information.

This really raised my interest because my daughter had an episode a few months ago that could have been something like this. We don't know for sure. The ER called it a panic attack, but said it was probably related to her meds, but that was also ruled out after the fact. It hasn't happened again so far.

I hope you find some answers and more importantly, some relief.
