Here's hoping I just bit off more than I could chew with regards to my VR tolerance this early, and I'll eventually be able to cope. I'd hate to think this is going to be a common thing.
You can build it up. It's pretty much like getting your sea legs. You stick with it, but don't push it, and eventually you develop a tolerance. Just don't try to push through the nausea itself. Once you start feeling bad, stop playing.
Nausea medicine also helps some people, so you can consider that as well if you need a pharmaceutical assist.
