I get this, not fun. I have a physical therapist who really helped me by showing me manuevers that really help. go to google and type in your vertigo wording and it will show you just what moves you need to do. I have had it for so long and in all the canals that the clinic filmed my eyes movements for training purposes. Once you learn the right technics for you, you can help yourself just by the exercises that you will see at the site.
Good Luck
