I've always had motion sickness but in the last few months, it has gotten steadily worse.
I get ill as a passenger if I don't stare out the window constantly, and when I'm a backseat passenger, I get ill no matter where I look.
I'm now getting it when I'm sitting still as well, when working on my computer or watching TV. Typically it's when I'm scrolling quickly or watching a video in First-Person, but has happened randomly as well.
I have checked and I'm not pregnant. I also get regular eye checks because I wear glasses.
Any suggestions as to what might be triggering it?
