I absolutely love spicy food, and it’s never affected my gut. I was actually confused when I read about people getting the shits after a curry and wondered if it was a joke. I’ve had curries so hot it caused people to recoil into a coughing and sweating fit after they dipped their finger in and had a taste and I have one every other day. I feel the burning in my mouth, my face turns red, my forehead sweats, my esophagus feels weird, but (tmi I know lol) when I go to the toilet I’m completely fine. no gut pains either.
As others have said, it started around my mid thirty’s. That also happens to be when I started growing my own ghost peppers… hmm. There is a big difference between a few slugs of a hot sauce and something truly marinated in heat. I have had a few spicy chicken sandwiches that you have sign a waiver (marketing bs) that have had the effect, but were surprisingly not that bad going in. Anyway. Up your game if you can’t feel it yet. If your mouth can still feel anything, you’re not hot yet. You should reach beyond the sweat and start feeling a pleasant dizzy feeling and no feeling in your mouth anymore.
