I did do the paqui one. There's no need for anything spicier lol it's not a matter of taste buds, it's about maintaining a healthy stomach lining

I have a pretty significant spice tolerance and did the OCC earlier this year. It was an uncomfortable mouth experience but the first 10 minutes immediately after were fine. The two hours after that of stomach pain followed by 10 minutes of projectile vomiting makes it completely irresponsible to recommend. It's a chemical irritant, not a spicy sensation
