Really don't need to panic - vertigo is an inner ear problem. I get it when I'm in elevators sometimes, so I can imagine being on a plane would be hell on the inner ear! (I've never flown myself, but I'm sure if I did I would be feeling like you are now!) Try dramamine or bonine. Be warned, bonine pills taste AWFUL and the taste is hard to get rid of, so I'd recommend taking it with flavored milk; the only thing that killed the taste for me!
