The BEST trip i've had so far was when I was drunk, my set and setting were perfect.
I didnt worry about smoking too much, I didn't have all the hype that usually comes with preparing the dose.
Me and two friends were having a relaxing night at home drinking, I was just about to "throw up and pass out" drunk when my best friend who was slightly more sober than myself and knew I had been struggling to relax before smoking prepared a big dose in a oil bubbler and said hey come here real quick.
I entered the room and he said DMT time, now that you're nice and relaxed! I said Absolutely!! He lit it up and held the bubbler for me while I took the hugest three rips I've yet managed.
I won't go into detail about this trip experience because i was saving it for a time when I felt like writing it all out, but overall it was the best experience I've had so far, and about 20 minutes later as the last effects were wearing off I realized I was completely sober from the alcohol and was able to drink 10 more beers before we hit the hay that night.
I don't think using DMT while otherwise intoxicated is a bad idea, as long as your head is still in the right place when you toke up...
