I never had this problem earlier but lately I have started feeling sick nausea/ vomitting, headache if I am in a moving vehicle on road. As I travel daily to work in company transport, it has a become a huge problem to curb it. Please advise what can be the cause of this problem n how can I cure it. The moment I get off the vehicle, I feel better instantly. But inside its constant feeling of vomitting n restlessness
