Wow, I really thought I was alone in this.
I suffer really badly from what I would describe as a panic attack.
It only happens when driving on motorways though.
It doesnt happen as a passenger, only when driving and is much worse when driving at night.

Ive been trying to find a cure for this for the past 2 or 3 years now. Ive been to the doctors who sent me to the ears, nose and throat hospital for various tests including balance tests, hearing tests etc.
Ive also had eye tests and nothing has cured it.
Im now at the stage where as soon as I enter a motorway the symtons start as I know whats coming.
I have found that if I have the heaters on cold and the window open its a little more bareable if that makes sense??
