Have you seen a doctor for your vertigo? I had a touch of it a while back and learned from my doctor about YouTube videos that show an exercise that can be done to help. In my case, the exercise cured the problem. No more vertigo and the cure was near instant.
That said, vertigo is caused by various things. It may not work for you. The exercises is called the Epley Maneuver. There are several videos about this. Look at a few and pick the one that makes best sense to you (if any).
