Give it some time.
My mother is almost completely debilitated by it, has had inner ear surgeries and is on meds for it.
I had a bad bout of it for a few months 2 years ago.
Given my mothers record it scared the crap out of me.
I thought my riding days were over.
Mine eventually subsided and for the most part has went away or I have learned to compensate.
My wife just went through it, its been about 2 months now, but her's is going away too.
I do wonder if it could be food (coffee) related as suggested.
My wife had swapped to decaf around the time her's started and I swore that was part of it.
