I just guess it would be an interesting experience, though I do agree it does sound unpleasant. As nearly all my Psychedelic drug experiences are so positive, it would be interesting to experience this other side first hand. I'd only ever plan on doing it once for the experience.
To be honest, I suffer from states of anhedonia and mild depression whilst I'm sober, who knows, maybe I may even end having a glowing experience. Besides I'd be interested in finding out which receptors it affects, sounds like it may be a potential antagonist at some of the 5HT receptors, hence the state of flattening and anhedonia described in the PIHKAL #7 entry.
