Does indeed sound like a typical case of vestibular syndrome (called such because it has no known cause). As for Meclizine usage, I have never had it help but it also is very unlikely to cause any harm. The correct dosage is vague, though, and often is listed as 1/2 to 2 tablets 2x a day (but leaves the weight of the patient out, which makes it a pretty broad dosage). One source lists a more accurate dosage, but also admits there is no research backing it up.
For vomiting due to vestibular disease, a drug like Cerenia is far more effective than is Meclizine anyway (but it is not over the counter- needs a script). Nothing I know of seems to help the dizziness, but in 95% of all cases, it resolves on its own (the other 5% may be caused by something like a brain tumor, infection etc.- SOMETHING that is never discovered in the majority of cases... which could explain why those few dogs do not improve). Time for resolution varies a lot from dog to dog, some improved in just a half hour while others take weeks to be able to stand up again.
