Vertigo, nausea, unable to see correctly and severe ringing in the ears. When an episode occurs I must lay down as it's too difficult to walk. The reason I asked about the Betahistine is I had heard on NPR an interview with a Dr. David Kaylie MD FAC an associate Professor of surgery head and neck and Communication Sciences at Duke University speak of Betahistine as a med that they had had success with for patients with Meniere's. Also that it has been used for Meniere's in Europe for decades. My ENT dr. was not familiar with it nor was my family dr.. Am hoping someone that has taken it can pass on an opinion and also how to find a doctor that is aware of this medication.
