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.
Translator here. They do make up stuff or omit stuff they don't like. Machine translation is fine for tourists or to translate a ikea manual in the wrong language. If there are stakes, risky. They got good enough to make sentences that look right so it can be tricky to spot the errors if you don't pay attention.
Numbers are typical errors. Sometimes it's there but the number has changed. Sometimes it's not there at all. Oh and if you have currencies a translators knows a document from the UK in pounds that is adapted for France will have to be converted in euros. Machines don't.
Generally speaking when a client wants to use machine translation, it costs them more money in the end because of the extra time needed to correct everything to a high human grade standard.
