Ive never anally administered a drug, but heres my suggestion: a) if you cant swallow it, just suck on it for 10 min then spit it out. or b) put a drop of vodka on the hit, then wedge as far up the anus as comfortably possible. the vodka will help it absorb.
I was thinking the same thing. Tap water has small amounts of chlorine in it, to clean the water. Chlorine, heat, UV rays and republicans are the four main enamys of acid. So yeah pure water (distilled water) is the best idea. But I'm not sure I'm following how putting it on your tongue makes you sick.
With LSD, no it wont make a difference. But with many other nausea inducing drugs rectal administration will significantly reduce nausea. But like the OP said its a mental thing, the rectal administration will definitely help.
