Yes, please leave the dramamine at home on track days. Putting your car on the roof at 120 mph because you were DUI is a lot worse than a case of motion sickness.
Before my Porsche life I use to do yacht racing. Bonine is a much better alternative for most people but simply eating light on track days along with some ginger snaps to control nausea is the best plan. Save the heavy chow for after the event.
