Moose,
I just wanted to say that you could have a case of Vertigo and not necessarily cervicogenic headaches. When Deb mentioned all of her symptoms in another post, they were identical to the ones I used to have. I, too, was given Meclizine a LONG time ago before they really figured out what the poblem was. But since you didn't mention headaches or neurological deficits so to speak down your arms and such, I really believe it may be something else altogether.
