Mine always triggers on my right (non mm ear). ENT tested and only right ear showed up. I do 2 minutes for each epley move.
Very interesting, my bppv was on my non mm ear as well. 2 minutes is nice and ample time so that's good.
As usual I'm a little different from most. 90 percent of the time my BPPV triggers on my right (mm) ear and seldom on the so called good ear. I always sleep on my left side out of fear of triggering spins if on my right.
