I have experienced an inverse correlation in my pepper consumption. When I first started eating peppers, and would get the occasional super hot (relatively speaking) pod, I got a HUGE endorphin rush to the point where my body would quiver, my face would feel like someone was tickling it with feathers, I felt lightheaded, and like I was high as hell! Now, that rarely happens, in part because my stomach does not agree with superhots, and I have experienced the full range of heat levels, so I am familiar with the sensation, and my body does not release nearly as many endorphins. My most recent endorphin rush of any significance was back in November, when I went on a fresh pepper chomping spree one night hanging out with some friends at my house. I was gradually nibbling through several Hot Lemon Drop peppers, which are pretty warm but don't hit my stomach hard at all, and next thing I realize, I am feeling floaty, mellow, and sweating nicely. I knew I had the buzz going on, so I enjoyed it quite well.
