HI - have you tried the medication, Nurtec? It's an antihistamine (prescription only) but sometimes the dizziness could be from a migraine headache. I suffered from vertigo for a long time and was finally helped somewhat when the vertigo specialist (ENT-neurologist) recommended I try this. I'm also trying chiropractic services which seems to be helping even more than Nurtec. I've discontinued the Nurtec now for awhile.
