I am not a real doctor, nor do I play one on TV, but I have cured two people of vertigo using the Epley Maneuver as learned on the internet.

It sounds like mumbo jumbo, but it is not. It was 100% successful the two times I administered it. I urge you to check it out. Vertigo is debilitating and this procedure only takes a couple minutes. Hope this helps.
