Yes, the Post Concussion Syndrome roller coaster can be quite a wild ride. It helps to look back and try to identify triggers that may have cause the relapse.

Car sickness is also common. There can be too much sensitivity to the physical movement of the car or a sensitivity to the movement of the visual objects outside the car. It helps to focus on things that are far from the car. Those things within a few car lengths will challenge your brain's ability to visually process.

I rarely had problems with sea sickness. I could relax and even lay down in a rocking boat. Now, I am very sensitive and have mastered the behavior know as 'barking at the seals.'
