Ketamine, LSD, DMT, Morphine, 3-meo-pcp, weed (want to make it edible), and DOC
Eat the weed, the LSD a little later, give myself a shot of morphine, smoke some DMT, go into a K-hole, smoke DMT when I come back out, plug the 3-meo-pcp and some DOC at the same time so I won't stop tripping on serotonergics when the LSD wears off, smoke more DMT and snort small bumps of K to see how much I need for an OBE when I am already so fucking high that when I stare at the ceiling, I think I am a lightbulb or one of the blades on my ceiling fan (on 3-meo-pcp, I can enter a state where I think I am whatever I am looking at. If I start a slideshow on a repeat loop that changes like every 30 or 60 seconds, I can experience myself believing I am all sorts of things if that is what I want to do. I can get fucking confused if someone walks into my room and I think I am that person and they are talking to me. If I have music playing, I will often think I am at a fucking concert). And I'll continue an orgy of drug abuse until I have been tripping my ass off for 30 or 40 hours, then let myself come down.
I'd probably want some strong salvia extract (or better, one of the long duration salvinorin analogs, MDMA, and GHB or at least 1,4-butanediol (I don't know if it is much different anyway, it is a GHB pro-drug that is quickly converted to GHB and is thought to be inactive until then). Maybe some muscimol as well so as to put something in those receptors. I always have benzos. A bit of meth for those receptors if I left them out. If any others are left unaltered, I need something to stick in them.
