That said, the stuff has as one of its side effects what a warning on the back of the bottle refers to as a "temporary flushing reaction." In other words, I turn red and my skin burns a lot and itches a little for about ten, fifteen minutes. The first couple of times I took it, this didn't happen. Then the first time, it was just my upper back, face, and neck. It was a little stronger the next time, and this time (it's just wearing off now) my whole upper body turned bright red (except for the part of my left elbow where I busted up my arm a little over a month ago), and burned so much that I couldn't tell whether or not it was unpleasant, since there was no pain, just heat. I could feel my pulse in my eardrums.
What I'm trying to say is that this would be kind of cool if it didn't get a little stronger each time. That's the part that worries me. Oh well, at least the pills are apparently vegetarian.
