I'm not the one who is downvoting you. I got rid of my Quest 3 because of VR sickness. Aside from causing severe sickness that took a couple of days to pass, it was too heavy and uncomfortable to wear.
Curiously, what games are you playing? I find that games that involve real world motion didn't match virtual world motion (ie, any racing or flying game), I feel sick within seconds, but games where the two worlds always match (ie, Beat Saber, Pokerstars VR, Superhot VR, Space Pirate Trainer), I could play for literally HOURS and feel fine.
VR sickness is the inverse of car sickness.
- VR FPS game: Visually moving while physically static.
- Car passenger in back seat: Physically moving while visually static (car interior).
