The maneuver does work and it is possible that they don't know about it.

I don't know if you can have someone do it for you but my Dr. showed Bill how to do it in case I got it again which I didn't, thank goodness.

I know what you are going through. I remember not being able to get up without getting dizzy. At the time my Dr. made house calls so he actually had to come to my house to help me with it.

Be careful and don't fall from having it. It does make everything seem to go round and round.
