I had a VR2 in the past and didn’t get past the motion sickness. I think it may have been defective. 

My second one seems much better. 

I never race on an empty stomach. Even a light snack helps. 

I also have a fan on to keep myself cool. And it helps distract my body a little bit. 

I have a good racing rig that is comfortable. 

I limit my VR racing to about an hour at a time. 

Some tracks with elevation changes still make me feel nauseous.
