Having dealt with this disease for over 30 years I have never read about it in fiction before, and I'm a huge reader, well I'm now reading a book called "Fluency" by Jennifer Wells, it's a sci-fi about humans finding an alien space ship just beyond Mars, the send a team to invistagte and one of the members is a linguist. When she first comes in contact with the alien's attempt to communicate she experiences a buzzing in her ears, since no other team member can hear it the flight surgeon tells our hero that she has Ménière's disease, with a full page description of the disease and treatments. I thought that was pretty cool.
Sent a message to the author via her Facebook page, thanking her for expanding awareness of MM. Surprisingly she responded! She told me that she didn't know anyone with it, just had an idea what she wanted, typed the symptoms into webmd and came up with Ménière's, she then "tweaked the symptoms to confuse the doctor and keep her readers guessing". I finished the book and told her I enjoyed it, downloaded her first book and will give that a try.
