Wow, the Epley maneuver doesn't help, huh? I don't think these dots would help either, as their movement wouldn't match the inner ear sensation you feel.
Not really, I've been to various docs for this.. one said BPPV attacks usually hit people 1-3x in a lifetime, I average that per year. Head MRI revealed nothing interesting. It's much diminished from its peak abuse of my system, but I have low-grade persistent vertigo that shows up if I move too fast, like turning in a closet.
