Thank you for your compassion. I can’t train the motion sickness away to the point where I am “cured”. It only works for a certain time. Then I have to play this game every day to have my peace. As I said, as soon as I take a break of 2 weeks, it’s back and I have to train it away again. I have tried this over and over again for the last 15 years. Train away, play through the game (e.g. shooter), take a break from the game because I don’t have time, buy a new shooter, train away, play through, etc. …
I don’t like that at all anymore. That’s why I only play games now where I don’t get motion sickness. But there are worse things. My computer doesn’t have to be VR-compatible and I can play flight simulations, racing simulations and strategy games without getting motion sickness. I have come to terms with it and it is not a problem.
