I've been having some trouble. Pre-flight jitters. I have been driving myself nuts for the past couple of weeks, trying to work up the courage to smoke a breakthrough dose. Usually I smoke lower ratio changa blends, but I've been wanting to try for a stronger experience. Every time I would feel like I was ready to go for a straight spice launch, something would come up. It was getting ridiculous. So I decided today was the day. I chickened out. I decided to smoke a 1:1:1 cappi, blue lotus changa instead. I was having a hard time working up to that. I finally found the resolve though, and loaded the changa into a water pipe. I tried to pull as slowly as possible, but I'm sure I burned some. I got about half of the dose, probably 30mg of dmt. Things started off great. Beautiful visuals. I saw a zebra with butterfly wings and an insectile face, flying in place against a constantly morphing background of interlocking M.C. Escher butterflies and bees. Unfortunately, the body load was heavy and not pleasant. I smoked 30mg more five minutes later. Same effects.
I started to get a horrible, toxic pain in my neck that radiated down my spine. I had a problem with lower back pain that resolved a few months ago, and suddenly that area (lower right) was hot and radiating pain again. It wasn't nearly as painful as my neck though. Other stuff happened during the trip, I saw and heard beautiful things, and had some entity contact. One with the voice of an announcer that morphed into Casey Kasem, who said: "This weeks top 40 trips include...." So, my trip was pleasant, even though I was in pain. This has happened to me before, with different batches of changa and differing qualities of spice. From near white fluffy crystals to waxy yellow stuff. This was a changa made from a dark yellow waxy crystal from a mhrb stb. Freeze precipitated from naptha. This was from one of the final pulls.
Was my pain from impurities? I doubt it. Was it psychologically induced? Tension from life in general, becoming more pronounced as I braced myself for a launch?

When I came down, I called a friend to talk with him about the pain. I was still tripping a little. I could still see the air a little bit. My neck still ached with a dirty pain. After talking on the phone for 15 minutes, the pain was gone. It has been 3 hours since I smoked. My back aches a tiny little bit and my neck feels a little tense. I also have a small headache, which I sometimes have after longer changa sessions. This one was short though.

Is this just a matter of me getting off my lazy ass and doing a re-x? Do I need a message? Maybe both?
Any input would be greatly appreciated.
Thanks.

Ok so I'm probably not going to be able to give you a full answer as this is the first report I've read like this....

But serotonin receptors are found all over the body. When I do DMT I get a huge body load (Not uncomfortable), that feels like energy running through every cell of my body. On large doses I will actually observe my limbs moving on their own...usually my hands want to rise off the bed into the air.

Is it possible that your body is causing muscle contractions in the area of your neck like my body does with my arms?

Like I said, not a perfect explanation, but food for thought. This molecule...this thing we call DMT interacts with almost eveyone in a slightly unique way.

Interesting idea. I have yet to have involuntary movements during a trip. Maybe you are on to something. I have some diazepam that I was prescribed as a muscle relaxant. I have heard that it reduces the potency of the trip, but I wonder if it reduces all aspects of the trip. Maybe it only damps down visual/mental effects.
Perhaps I'll take 10mg of Diazepam and see if the neck thing happens. For now though, I'll keep that on the back burner until I have heard more theories.

I'm still relatively inexperienced with this substance. I may draw the ire of some by thinking that changa is somewhat analogous to ayahuasca. If this is the case, could a purge of sorts be taking place, but not as a liquid excretion, but an electrical purge, causing intense muscular contractions? Just an idea.
