I’m not sanguine about my options. I’ve talked to various doctors about this over the years and done plenty of research and experimentation. The consensus is it’s a neurological problem in the interface between my visual cortex and my balance mechanism. What my eyes and my proprioception feels is different from what my vestibular balance is indicating. This is why it can hit me in a cinema when I’m not actually in motion at all. This happens to most people as they age, but it hit me early. Very early.
Unfortunately it kinda sneaks up on me. If I know I’m going on a boat or an airplane I can take medication and be fine, but if I’m driving home late and an unexpected rainstorm hits it can be a real problem. I keep meclazine in my pickup to take if that happens, but once it’s happened it takes a while for the medication to counteract it. Some movies are fine, but some sneak up on me. I had to walk out of the 2009 Star Trek and lay down in the lobby to wait for my friends. I later watched it on a small screen and it was a lot better. Shouldn’t have bothered. It’s a dumb movie.
