Vertigo - has anyone resolved the sudden onset of vertigo

I've recently acquired a case of apparent vertigo, and my ENT doctor offered no help other than physical therapy as treatment. I'm taking meclizine (aka Antivert) which helps somewhat, but I have significant imbalance even so. My loss of balance and dizziness lasts from the time I get out of bed, for about 90 minutes, after which it diminishes in effect, but I feel unsteady all day. Ginko biloba? Dramamine? TIA!
