This is a reply to the dizziness-I have had Meneres Disease for 45 years, 20 years without a proper diagnosis, I am not sure if it is lumped with PPPD or not. The cause is an imbalance of fluid in the inner ear that produces the dizziness and vertigo. Meclazine is an over-the-counter medication that really helps, but again is another med. I finally learned that sodium, salt, was my Achilles heal, if I limit my intake to 1000 mg or less a day I have no problems. That can be a real problem with all of our processed foods, however limiting that did two things, it got rid of the dizziness and also made me eat a much better diet, so it was a win-win! Through the years I’ve found not many doctors talk about the sodium component or even mention it, however that is a primary cause!
