Of course I did! It is Amazing. Most visual psychedelic I ever did. Kicks in IMMEDIATELY. I mean: when you inhale, your lung is not even full, it kicks in. If you are experienced enough you'll be able to take two hits, before you Melt into the armchair. Someone should be there to take the pipe from your hand when this happens.
I suggest you to do it in a quiet place, in daylight, no music, no movement, if you close your eyes it will be perfect. 30 minutes and It Is Gone, you can take another hit or just... post-process [after every serious trip you need to post-process]
DMT is fucking amazing for people who love acid, but don't have That much time anymore [family, etc]. No after-effects!!
Namaste
