I'm not sure about your DMT experience ANC but mine was far removed from what your describing. While it's true it doesn't last that long I'm not sure if I would want to to last any longer than it does. I can't vouch for salvia as I have never tried it but heard bad things. I was just making people aware of DMT as a possible alternative because I'm guessing that people who are interested in salvia probably want to trip out on something. DMT is by far the most psychadelic I have ever been and I have experienced many psychadelics. I'm not sure about your administration and dosage but I have to concluded that someone who describes DMT as quote "maybe making you run at a slightly more powerfull gear for a few minutes" may have not done enough or got some weak shit because I tripped balls with unimaginable visuals. I mean the craziest shit I've ever seen. No not like shit that was really there looked crazy, I mean I was seeing all kinds of shit that wasn't really there. Never had that on mushrooms, LSD, mesculine, not even close.
Look I get where you are, and I also at a point in time had to realy keep my wits on me just to light up another pipe... but the whole experience changed over time... now, I can after smokeing (not spontaneously), go as deep as I want and still be able to return to the "consensual" reality and pretty much do anything I guess at will. Its just not such an oppressive thing... it appears to be at first glance, but just chalenge it, just defy it, you will see that you have been in control all along. It reminds me of once when I administered soem to a friend, after a few minutes he had about as much as he could handle for a first time... he asked me "can I open my eyes?" I mean realy...
Lol, you know what is even more awesome on DMT, is seeing things that are realy there but you normaly don't see... As an example, with DMT used open eyed in nature, one can clearly see mineral deposits in rocks, or something else I enjoyed, once, whatever filter our brain employs to make white things seem white even under a blue sky, became undone, everythign became blue green... it was quite a trip and very out of character for me, but I was laughing like a lunatic.
