CC - The B&D exercises can be helpful and lots of therapists do them. However, IMHO the Epley manoeuver is much more effective. The downside is that you need someone to do it to you. A vestibular therapist (PT) or MD can do it. Here's a link, if you click on the diagram on the right it will walk you through the technique.

I did not read the website so I don't know if this is in there, but you should know that if someone does the Epley on you you should sleep in a sitting position for about 1 week afterward.

Hope that helps.
