Oh yuck! I hate that feeling. Do you have any meclazine or Dramamine/Bonine... stuff? If you can take it, and the blue pill and try to sleep it off, it might let up by morning.

Sometimes I have to sleep in my recliner with my head wedged in one place or there will be no sleep. If you're having vertigo in the dark, make sure there is a clock radio or some small source of light to focus your eyes on. It will help you "hold still".

I soooo feel for you, it's horrible.
