Scariest bit was when it first 'struck' - woke up, got out of bed (sounding like a Beatles song now ) and whoah!! Massive vertigo, room kept moving etc. I must admit I was seriously worried and thinking "Oh shit!"
Bit of net research and reading gave some hope and I really was amazed that the simple exercise fixed it. That was a few years ago and so far not a sign of it since.
