Meniere's Disease Support Group
Meniere's disease is a balance disorder of the inner ear. The symptoms of Meniere's are variable; not all sufferers experience the same symptoms. However, "classic Meniere's" is considered to comprise the following four symptoms: Periodic episodes of rotary vertigo, hearing loss, tinnitus, and a sensation of fullness or pressure in one or both ears.
I wonder if there is a way you could find out information about food etc. that could help you plan for a realistic trip.
Congrats on feeling better, by the way. That is big!
Blessings.
