meniere's disease
"I have been inflicted with an inner ear problem for 40 years. I have been to so many specialist who could not find the cause.  The flare ups are devastating and cause me to have dizzy spells that last for a few minutes each time.  It occurs when I change head positions in a hurry.  When the episodes occur, a combination of Valium and a vertigo medicine works fine. After a few days, I'm back to normal. It has been a blessing and allowed me to keep my job in law enforcement for many years until I retired.  The only other alternative was to surgically serve my nerves in my ears so that I would not experience the symptoms. The doctors all agreed this was too drastic and if the medicine works, to stay with it."
