Howdy!

Since I drive a heck of a lot, this could be a serious problem. Several times on longer trips, I feel briefly faint. Seems my jaw gets very tight and my grip on the wheel tightens. I don't know if that's caused by the anxiety of my very brief episodes, or it's another symptom. I really need to stress the fact it only happens while driving. The higher the speed, the worse it is. Busy, congested city traffic cause no problems for me.

I guess i'm thinking it's got some sort of visual trigger, as i'd mentioned the higher the speed, the worse it gets. I should also mention I have meniere's disease, which seems to be behaving itself for the last several years, save for some mild tinnitus.

I do keep my eyes moving, but I must admit, when this happens, I tend to freeze up a bit, and then force myself to turn my eyes and head. So i'm tentatively ruling out any road hypnosis.

Any thoughts on this?
