Oh My, that's horrible, Laura. I've had a few episodes, but not like yours. My nephew had an attack while driving his truck to work, and had to ask a pedestrian to call 911. They hospital thought he was on drugs. I don't remember the tests, but they gace him something for nausea and antibiotics. He's been Ok since, but since he's an electrician, and climbs ladders, it's always on his mind.

I hope it's nothing serious, but I'm glad you're going for tests since vertigo is not normal. Sorry you had to miss your boating trip. Wishing you the best...
