Sorry to hear of your battle with vertigo. It is one of the symptoms I dislike the most. When I get vertigo my only remedy has been to lie down and rest. When I had a bad bout in 1982 I would literally spin my eyes in the opposite direction to make it stop. I felt as though I was actually going to roll out of bed and held onto either side of my mattress.
It appears that you have the right meds, but CNS vertigo does not always respond to meds (just like CNS pain). If you find something other than meds, please shar your experiences. Meanwhile, I really recommend you lay aside chores and rest because tomorrow will still arrive with or without a clean house! While TV and reading can make it worse, I would try closing your eyes and listen to an audio book, music, or even the TV or a movie.
