Wow. That was really, really nice.
This time I took six or seven sizable hits, in a row. At first, I just felt a nondescript rush of intoxication. Then, my vision went blurry, and my thoughts seemed to be relaxed and washed away, and I just started quivering, shaking. Not in an anxious way -- in a cold-trying-to-get-warm way. I sat there shivering for a good five minutes or so, and as the shivering continued, a powerful warm glow spread throughout my entire body. It was as if the intense shivering were giving me a thorough, full-body massage, and any tension that may have existed anywhere in my body was eased.
Afterward, I felt sedated and highly euphoric, exactly like I imagine drugs like heroin to feel. Like the feeling of sitting in front of ruby red, glowing coals, on a cold wintery night, after a hearty meal. In fact, I felt so good, that I almost didn't notice the transition into orgasm. :D
JesusGreen, at this point I don't really think you can get a DMT-breakthrough type experience with DPT. DPT is a wonderful substance, with its own unique experience to offer, but you won't get anything approaching a DMT breakthrough. DMT is a very cosmic, spiritual drug, and its trip is focused on a divine, alien energy. DPT is a much more down-to-earth psychedelic, focused on the familiar, physical here-and-now. (Which could explain why it seems much less threatening.)
I could be totally wrong. Maybe I still haven't pushed DPT far enough for the flying-through-hyperspace type trip. Anyway, those are my feelings at this point.
EDIT: You know, something just occurred to me. DPT shares a certain quality with LSD that I haven't seen in any other psychedelic. They are the only two serotonergics I have tried which actually have a positive push to them. Positive emotions in a trip on any other substance are not really guaranteed, and usually result from gaining insight, or enhanced music appreciation, or some such effect. But on DPT and LSD, there is an intrinsic positivity in the trip itself, seemingly due to some sort of medicinal, healing effect on the body.
