Do you have a history of migraines? If you do experience these debilitating headaches you may be more likely to develop motion sickness, says Dr. Akira Ishiyama, of the University of California-Los Angeles medical centre. He suggests these tips to ease motion sickness:

-Drivers rarely get sick. If you can't drive, sit in the front passenger seat because it will allow you to see the road ahead.

-Try to avoid sitting in the back seat or in a rear-facing seat of a vehicle.

-Don't read while riding in a vehicle.

-Avoid greasy foods when travelling.

-Keep the window open for fresh air.

-For children who get carsick, have them keep their heads as still as possible if they have symptoms and try to distract them from their discomfort. Stop and let them walk around if they feel ill.

Assuming it can work both ways - if you have a history of motion sickness, you could also be experiencing migraines. It sounds like maybe you should keep the migraine medication close at hand too – all that motion sickness, not to mention the crying carsick kids, could give you one splitting headache.
