These are literally the most appropriate words I can think of to describe my experience of eating the Trinidad Moruga Scorpian.
This was one of the most uncomfortable moments of my entire life. All of the same effects were there as with the Ghost Pepper, but they were all so much worse. My entire face and throat felt like it was vibrating. My lips felt like they were on fire. My mouth, tongue and throat felt like I had swallowed sand, or thumbtacks. Red hot thumbtacks.
Like Hellraiser, this pepper introduced me to new sensations in levels of intensity which were previously unimaginable.
I have literally never felt anything like this in my entire life...
