If you haven't already tried it, I'd suggest harmalas (syrian rue extract, cappi, etc)...I used to have the same problem, I wanted more understanding from the experience, more memory, less mind-fuckery...Harmalas cancelled that crazy "bounce around in hyperspace" shit out...Its as if the harmalas are actually stronger than the dmt, but in a different way, not in an intense way, but a quiet, wise, powerful way...It keeps the DMT from taking your mind beyond realms of non-understanding, and instead keeps you grounded, to the point where you can see ancient symbolism in everything you see...every breath carries with it a wave of deep conscious understanding, something that DMT can rarely do on its own...DMT is alien...Dmt and Harmalas are much more spiritual...Just buy some harmala extract, put it in a gelcap, eat it, wait 20-25 mins, and vape away repeatedly! I like to call it Suburbauasca...lol...Good luck man, and for those other freaky plants (lol), make sure to research the active as well as inactive alkaloids, best to be prepared, rather than die in your bathroom from a gnarly allergic reaction to the bumbawee-wee plant, known only to african shamans, and not yet studied in western culture...lol...ya never know! Happy Exploring!
