My Dad had vertigo before he passed away, kept him from enjoying a full life the last two years. Ironically he was experiencing a lot of improvement before he died, primarily from getting sufficient hydration. Before I suggested this and he began drinking tons of water he just drank coffee, milk and scotch (one or two drinks per day). He had gone from taking 16 pills per day to just a baby aspirin; was feeling much better. Most people don't drink enough water. Have you considered this possibility?
