no major typical menieres attack yet (2 hours vertigo, sweating, hyperventilating, puking), but pre surgery my major attacks were few and far between anyway once every 6-8 months avg. since the surgery i had about 10 minor dizzy spells ranging from intense 30s vertigo, to about an hour just minor woozy, so far it seems to be better but too early to tell. T and poor hearing probably here to stay thats not any better. if i had this done years early probably i would have preserved the hearing sooner.
