I've never puked or had sickness, but have definitely felt queasy when things felt off.
I downloaded a drum game demo for PS VR2 and I guess because it is buggy, it put me almost below the floor which felt really weird. I think that would make people feel sick. I ended up restarting the game because there was no other way to fix that. The positioning was weird, but some adjustment can make it somewhat comfortable. It was a fun game.
With PS VR1, I played Ace Combat and felt fine. I guess since I like playing it from a first person view without a VR headset anyway, so there wasn't much I needed to get used to. Felt the same way I felt playing Gran Turismo 7 on VR2.
Farpoint was the most time I spent with PS VR1 because it was pretty immersive. I mean shit, monsters jumping out at you like that and then blowing them away with the VR gun was super fun. I can only hope they bring a VR Gun to PS VR2. I wasn't used to Farpoint VR at first, so I played a short game and got tired, but things got better with the more I played it.
The gun controller compelled me to buy VR1, so yes I hope hope hope they bring one to VR2. Not that the way VR2 goes isn't cool or anything with having to make movements to open your coat or aim and reload a pistol, shotgun or sniper.
I played Resident Evil VR demo which again was super nice. A VR Gun would be more appropriate for that game, but sure the VR2 controllers work as well. I didn't get nauseous, but a closeup with zombies along with 3D audio was insane.
It looks like there is a "workout" game for VR2 already, but I'm gonna wait to see. Creed I got for VR1, but didn't play it much, so I don't think I will get it for VR2. If I wanna box, I'll just go on PS4's VR1.
Anyway, I haven't puked or gotten sick as you can see from the above, but for sure the drum game's positioning oddity did not make me feel so good at first. Probably the worst I've felt with VR in general. VR games have to make sure to position the player appropriately when getting started or else f**k that game.
