Start with the following simple exercises and work your way to longer and stronger. Do them every day for a month, and your motion sickness should be gone:
1. Neck rolls with your eyes open, very slowly, three times each way; do not stress your neck. You can get enough with half a roll. After a week, try it with your eyes closed and see if you can tolerate it one time. Add in another time with your eyes closed as your tolerance increases.
2. Log rolls on the floor with your arms overhead, as slow as you can, eyes open three times each way as slowly as you can. After a week, add in eyes closed as above.
3. Chair turns - sit in a swivel chair and have someone turn you SLOWLY (one minute per rotation), once in each direction with your eyes open. Do with your eyes closed as above.
This takes less than 5 minutes a day, and in a month, you will be fine!! I now can read in the car, myself.
Do this with your daughter, too, and have FUN!
