constant negative feeling while tripping

Hey. SWIM is a reasonably experienced tripper, he has done 25i-nbome (regretedly I know), 2cb (have done 33mg hits 4 times), 2ci, 2ce (20mg hits twice), and lsd (220-330ug trips). I usually thoroughly enjoy psychadelics, with a passion.

However, the last 2 times I have tripped (a 33mg 2cb trip, and a 220ug lsd trip), SWIM has felt something negative constantly throughout. I have experienced a bad trip before (I was on 2ce when I experienced a very bad incident and had to go to A&E with 2 seriously hurt friends, this sent me into a bad trip), however this didn't feel like that did. These last 2 times, it is hard to describe, I just experienced a constant irritating/negative/painful feeling non-stop in my body, the location of the sensation changing. At points in the night, especially the LSD one, I could consciously think and isolate this feeling, and truly acknowledge it. I have also noticed sometimes the visuals are slightly more intense in these 2 trips, however my memory may be deceiving me. I have a number of possible explanations but they don't seem like the true reason behind this feeling;
1. On the negative 2cb trip, I was in a room which people claim causes an intense trip, so many it was too intense for me
2. On the LSD trip, a close friend was texting me telling me that some weed I smoked with him the day before sent him into a very dark and worrying trip (he supplied the weed, even though I've been smoking it for years regularly), maybe this was in my conscious all night worrying?
3. Maybe my tolerance has gone down and they were both just too intense for me (seems unlikely as on the 2cb trip I took half, it didn't really do much, then took the other half, and why would a tolerance go down? And everything else to do with the trip I can handle, its just this isolated constant iritating negative feeling which is very hard to express in words)

Does anybody have an idea as to what is causing this? As I wish to try DMT/Changra and trip more in the future, but am scared of this happening again.

Thanks for your time in advance

 

Shit happens.. either leave them alone for a while and wait for a different area of life, or up the dose and see what happens.

Oh, and..

 

It sounds like anxiety.

 

Psychedelics are very unpredictable. The same stuff can cause two totally different experiences. It all depends on your set and setting and what your bringing into the trip. Sometimes you have to be prepared to have a rougher one.

 

Pretty much agree with what has been said but I'll add that for 2cx chems in particular, it's not that uncommon for physical complaints to manifest.

I'd reccommend Changa over isolated DMT if you're looking for a smoother trip.
