This. I pushed myself the first time I used VR, and it was a horrible mistake that left me in bed for a few hours afterwards feeling like I was going to die. If your brain is telling you to stop, just stop. 

I think it's pretty hard to build up resistance, honestly. Most VR games are shit, so there isn't much to play, which means the headset goes unused for months, and any tolerance you built up crumbles away. I'm better now than I once was, but it's a very slow process.
