Take it easy, you'll get your vr legs eventually. The key for me was to learn to detect when my body was starting to feel bad, stop immediately and go take a break. If you stop the symptoms early you can take regular short breaks instead of being drowsy all night.
Also, find some easier games for your stomach. Typically, stuff in a vehicle/plane/spaceship is easier for the brain because it understands something is moving but not you.
Static games work too. Beat saber is the classic but I'd like to recommend SynthRider.
Also, play around with the settings when you're fresh and see what works. The black blinders on the side help most people but it make nausea worse for me.
I think it's still a migration of a rather knowledgeable part of the windows users. I did migrate a year ago because of frustrations from windows pop ups showing up like they own the computer.
I a still reluctant to recommend it to my partner who is comfortable with windows but not really techy. As long as Linux works, it works. But when you need something a bit more involved or something breaks, the terminal will be harder for those users who might not have ever opened CMD in windows.
