OMG, I had this about a year ago, woke up with it - I feel your pain. Depending on your age, I think it last longer/shorter. I am 50, it seriously took about a week before the world stopped spinning and after that it was sporatic for about a month or so, nothing horrible but certain movements brought it on, my mom who is 82 also had it and it lasted quite a bit longer and still lingers.
I didn't take any medication for it, because dr. said the medication was almost worse than the symptons, just toughed it out, couldn't drive for a day or two, but after that you adjust to it (my mom told me that, and she was completely correct)
Feel better- it's a horrible feeling when your even laying down and the world is still moving..
