Seems your experiences are very similar to mine.
Recently all psychedelics except DMT leave me very frustrated because I never get where I want to be, in my head and in terms of visuals.
Generally when I do high doses of acid I do it all at once at the start of the night which may have something to do with it but I'm now convinced that mushrooms just don't work for me very well anymore. I did 5 grams of cubensis yesterday and got 0 visuals but a nice body high. If I tried really really hard I could notice a slight pattern.
Forums across the internet just make me think that people lie about the visuals they get. I saw a post on one totally random forum before while browsing that said this:
"Lol, I've seen some fucking amazing shit on LSD...
Full fledged alien ships attacking earth (I was hiding in the porta-potty wit hmy wife guarding the door)
Mountains totaly changeing shape.
Little round clouds forming a vortex shaped spiral, miles accross
The ocean inverting colours to change into electric blue asfar as the eye can see.
Streets breaking up and the houses drifting apart with bright orange magma streaming below and between.
12 foot tall dogs dragging their owners down the street."
I read this and thought to myself.... I get nothing even CLOSE to this. I imagine all this is speaking from pure jealousy. Extreme jealousy. But psychedelics are a big part of my life and have been for a few years now and I just feel like I'm not getting as much out of them as most people are able too.
O well. Try try try again ha.
No drug, not even alcohol, causes the fundamental ills of society. If we're looking for the source of our troubles, we shouldn't test people for drugs, we should test them for stupidity, ignorance, greed and love of power. ~P.J. O'Rourke
