Oh, RIP to the outside world.
I know that feeling. I can't play 3rd person shooters or I'll get hella motion sick. PUBG??? I'll throw the fuck up. When I was playing COD and took any sort of break say, 3 weeks, it would take me a couple of hours to get the eyes right. That wasn't as bad, but I did get a headache. The FPS motion sickness is real.
