I hope this topic isn't too silly.

I've been doing well, I guess. Been taking a vitamin regiment and being easy. Today during Easter though we were over at my family's and my girlfriend wanted a tour of the woods. I didn't think much of it at the time. We went on the golfcart and drove around the trails for fifteen minutes.

About a half an hour after (around 2:30) until now (9:00) I've been dizzy and nauseous ever sense. Am I going to trigger a concussion or am I now just, thanks to PCS, more susceptible to motion sickness?
