One other thing Molly, I would always get the dizziness, feel like I was going to faint, and rapid heartbeat, and sometimes but not always I would start hyperventilating where I would have to breathe into a bag...I don't think I worded it very well and just wanted to let you know that the hyperventilating didn't happen each time so it sounds the same as what I experienced. It was definitely completely different than a seizure (or at least in my case).
Hope that helps!
