Vertigo

I was woken from a sound sleep early yesterday morning to the sensation of being whipped around my bedroom. It happened a few more times and my hubby took me to the ER. Doc said I am experiencing vertigo, and said I should follow up with my GP and a neurologist, which I am doing today and tomorrow. I stayed home from work today as I'm still pretty dizzy, despite the anti-vertigo meds.
I have NEVER experienced anything even remotely like this in my life! I actually feel better if I sit up and stay relatively still. That's how I'm able to sit and type right now. But, I'm very tired and sleepy. But when I lie down the spinning is sometimes worse than if I'm upright.
So weird. I hope I can get some answers soon!
