I had many light-headedness and dizzy issues with my PCS. This has gradually gotten better with rest, time, and as little stress as possible. I was also on anti-depressants (Effexor) for anxiety attacks and PTSD from the PCS. I do believe this helped get me over the worst of it.

I like the ear plug recommendation - I still use ear plugs any time I'm feeling overwhelmed. And I've learned to meditate - not super intense, ultra focussed meditating. Just enough on a bus, for example, to calm myself down and take a few deep breaths. I got off caffeine too. I drink de caff now and feel a little more calm.

Flying (which I was worried about) did not bother me. It's tiring, so you have to watch your fatigue, but the actual flying was fine - better than driving.

Hang in there - it does get better.
