motion sickness
"Our six year old gets terrible motion sickness even on short trips.  We recently went on vacation and the drive was proving to be too much for her.  She threw up the whole day and then some the next even after she was out of the car - really heartbreaking. We purchased dimenhydrinate at the suggestion of the pharmacist and she was perfectly fine in 20 minutes.  We finished our drive from Canada to North Carolina and she was completely healthy and happy the entire trip. FABULOUS!"
