I was getting regular dizzy spells recently (well, still am). Have been for the last few months. I went to the doctor to get it checked, and like always she had a two second look, asked me a couple of questioned and conjured a diagnosis out of the air (I'm sure she makes these things up). She said it was a virus of the balance organs in my ears and the only way to cure it was to cut down on salt and more vitamin C. I've been doing that, still no improvement, so if your doc recommends that...!
