I tasted the sauces and salsa, left the store and my stomach started to hurt. Bad; 10 on a 1-10 scale. Thankfully, I was with a friend. I sat down on a bench and broke out in a cold sweat. Everywhere, I touched my shin, pulling my leg in to help with the pain and it was soaked. Friend and I still had to get a shuttle, get back to our hotel in time for our scheduled taxi, and get to the airport. We were 3/10 mile from the shuttle stop and I didn't think I would make it.
Friend is lovely, but not fast in a crisis. I couldn't even think. At one point I was really dizzy. Friend said, I was ghost white and my lips were blue. I had her get me some water. I sucked that down. Another glass of water. I told myself "This is going to last for 10 minutes, you can hang in for 10 minutes." (I don't know why I thought 10 minutes, but that's what I decided.) I was starting to worry that I'd done permanent damage to my stomach/ small intestine and then... it lifted. We walked to the shuttle stop, made the shuttle, and I was at the airport googling "ghost pepper reactions" in an hour.
The "wisdom" on ghost pepper reactions comes from the world of competitive eating. Don't eat them on an empty stomach (that ship sailed!) and, if you have intense pain, drink full fat chocolate milk (another ship just left port!) I had a turkey and cheese wrap and some dark chocolate at the airport and then chips on the plane. That was enough fat and enough food that the peppers didn't exact any other torture.
I'd bought a bottle of one of the sauces and was a little afraid to eat it. But, I decided I needed to get back on the horse and I've eaten it with food with no problem.
If your friend's info is correct, I shouldn't catch a cold for years.
