I am somewhat prone to it, and I got seasick for about 12 hours from 30 minutes of sedate VR once. Eventually I realized what I needed to do was go outside and walk around to reset things. I haven't had anything that bad since- spending a bit more time in VR helps a lot- but it's not like I can just hand someone a headset and tell them to try it for more than a couple minutes without risking ruining their day.
