I also witnessed some probable seizure symptoms with my XA - I thought he was having a stroke. He was hallucinating, he had partial paralysis, didn't seem to be breathing properly - it was terrifying. In spite of that, he was always baffled, and even pissed, if/when I called the EMTS. Really?? Geez.
I agree that peace and calm can be reclaimed! I am another example. While not married, my XA and I have loved each other for many years. Parting from him was excruciating for me, and I myself suffered full-on withdrawal (no seizures, tho, *whew*).
But I don't have that awful, hyper-vigilant feeling anymore. I have so much more patience and energy for other things. Definitely a relief. Even when I'm sad, I'm relieved that I can CRY IN PEACE!!
