I had a dreadful attack of vertigo about two or three weeks ago that literally 'flattened' me! Mine seems to be a genetic predisposition to Meniere's Disease (runs in our family as my aunt had it, my mom has it mildly and my daughter also has it) I've only had two attacks in ten years but when I get it, I can 'proudly' say, that no one in my family gets it as bad as I do! I'm so proud.....well actually no, because like some here have said, it's absolutely awful.
In reading up on it, I discovered that some folks live with it constantly and it completely ruins their lives! You don't know when it will happen so driving becomes an issue, going shopping, holidays ruined...... I can live with an attack every ten years compared to what some of those folks deal with.
