Thanks for posting this. I guess I'd have to find out what type of vertigo I have first, but these exercises are good to know about. I did one set of them and instead of feeling dizzy on the way down, I felt dizzy once sitting upright again. That might mean something about what direction of movement I'm effected by (if that's even how it works). I never heard about the displaced crystals though...it sounds so permanent :(. Hopefully, there's an answer out there. When the time comes, I will see a doctor for this.
