I woke up this afternoon feeling fine. A couple of hours later I was getting up from the couch and I nearly fell over because I was dizzy. It's usually not too bad unless my head changes elevation. If I bend over everything starts spinning. Does anyone have any ideas as to what would cause this? It happens to me from time to time. The last time it happened it was so bad that every time I moved my head at all I would get so nauseous that I'd have to throw up. THAT was not pleasant.
