I developed Menieres disease and I would say it was linked to stress, I did a lot of research on possible causes and joined the Menieres disease society - ( UK) they recommend stopping drinking instant coffee ( some chemical they put in it to make the froth is not good ) stop taking Ibuprofen ( due to stress I was popping them like sweets ) cut down on salt, stop eating artificial sweeteners. I also found that if I was on the phone a lot while on the computer, my head position could trigger an episode. In fact , thinking about it , it was when the relationship I was in began to show itself as toxic as well as when my mother ( one of the authors of my toxic life story ) developed Alzheimer's. I hadn't made the link before , but thinking about it , if there isn't it was a big coincidence !!
