Yes my wife once suffered the same. Many months would go by without any problems and then, wham, it would hit her hard.
These vertigo attacks are totally debilitating. Waiting for them to hit and then taking a drug to relieve the symptoms is a tough route to go. It's better to get down to the root cause and prevent the vertigo attacks, if you can. My wife and I were lucky in that we found something that worked for her. Frankly, based upon my experience, most doctors don't have a clue how to treat this disease. :wave:
