benign paroxysmal positional vertigo. It was moderate to severe. I got really nauseous just sitting up in bed. Had to nap it off until 12:30. Got up very slowly, held on to the walls and furniture to aid in walking, and didn't move my head from its downward tilt position. I feel better now and can actually eat my first meal of the day (It's now 2:36, I'm ravenous).
