Its been 3 years , i always feel nauseous when i travel in car. I dont like the citrus flavoured car freshener the uber driver uses and also i think its because of the Ac too. But this nausea doesnt just go away when i get down from the car, it persists for few hours. The uneasy feeling a mild headache and the urge to throw up is very high after a car ride. Please suggest what should i do? Or if i need to visit a doctor regarding this.
