I've tried it a few times with some friends--probably only three or four experiences. The first couple of times it was a nice, relaxing yet stimulating buzz; it was similar to a Thai strain of K@ with less euphoria. The last time, however, I got terribly over-stimulated and jittery. It was most likely the poly-stimulant use at the time that was at fault rather than the nut being inconsistent, though. It's worth a shot if you're looking for a different kind of stimulation or to switch up your morning ritual.
