Motion sickness

[schomosport]

I am suffering from motion sickness at the wheel - so much so that I am having to abort test sessions because I feel too ill to continue. This was never a problem with saloon cars but since switching to single seaters a few years ago it has become a recurring problem. Very light breakfast, nothing else during the day other than water and coffee but still problems.

Has anyone else experienced this and if so how did you cure it, if at all? Unfortunately most over the counter or prescription anti-nausea medicines have possible side effects (drowsiness, blurred vision) totally incompatible with circuit driving.
