I had it about five years ago to the point that I too eneded up in the emergency room. I also was given meclizine, and it DID help. Mainly it was just time that helped me most. Slowly got better every day for about two weeks. It was scary at first, but once I knew what it was, I was no longer as scared of it.The rx they gave him was for meclizine 25 mg. Yesterday it seemed to do okay by him but today he is like a drunken soldier. He also takes fexofenodrine which is also an antihistamine....could he be overdosing on antihistamine? Our dr said the only other thing he could give him is valium, but that would make him ultra sleepy...oh good! a sleepy dizzy guy??? I said no thanks. Any ideas?
