@LittleJem shrooms absolutely help when I have access. I usually micro dose, unless I have a specific intention for a trip. lsd I haven't touched in over a decade unfortunately. that said, I worry somewhat about further ego dissolution with acid more so than shrooms despite my preference for lsd. additionally I worry about how taking more than a micro dose of any hallucinogen might impact my dissociative symptoms, though shrooms often help chill my psychosis out and erase 50% of anxiety and depressive or manic symptoms for me. so I guess I can't be certain. at this point, I'm prescribed an adequate amount of medical cannabis to treat a few diagnoses, and that more or less helps enough. though if I lived alone I would likely take hallucinogens much much more often. my roomies are fairly judgmental about the boogeyman monster that encompasses all things "illegal". if I didn't actually have respect for them and if I hadn't known them all as long and well as I have, I'd just store and maybe use "illegal" shit in my home.
I appreciate that you thought of hallucinogens as migraine treatment - honestly, it does help. nothing completely removes any problem for me but shrooms sure make things a lot closer to manageable.
* edit to add that due to my history with drug abuse and addiction I may be denied access to treatments like hallucinogens for migraines or MDMA for my PTSD, though I've been 'clean' around 10 years, so I dunno..
