There are four options:

1. Read a book in a moving vehicle

2. View a movie on a laptop in a moving vehicle

3. Read email on mobile device anywhere for more than 2 minutes

4. Play brightly colored, hyerpactive Japanese games on the Nintendo DS (games like Chibi-Robo and Animal Crossing. Mario Kart also can too)

Then feel dizzy and super-uncomfortable along with other symptoms for up to one hour.

Only known remedies are sleep and hot shower.
