I think it does get worse. I used to be able to read on trains,but can’t anymore. I bought a cheap pair of headphones and listen to music instead. I prefer sitting facing the direction of the train. Unfortunately I have vertigo, and have also found that air travel gives me excruciating ear pain and temporary deafness. I wear wristbands, and take stugeron on sleeper trains. We’re travelling to northern Spain, by train, in April and sailing back on Brittany Ferries. I’d appreciate advice on ferry travel, because I haven’t done it for years, and am a bit apprehensive! Will probably take travel sickness pills, but would appreciate others’views on the best ones.
