Migraine medicine and other kinds of medicine I was given did not work at the time, so thinking they might be cluster headaches I turned to 4-aco-dmt, which is psilocin without the psilocybin, so no stomach nausea, but a bit weaker. It didn't stop a migraine once it had started, but it did work as a preventative. I did a little bit larger than a microdose once a week and had no pain, no migraines, no problems, for quite a long time. (A regular full sized dose I could take once every 12 days without migraines.)
I turned to 4-aco over mushrooms, because it was legal at the time, and no nausea. I believe it's still legal today, but I haven't kept up. Today, mushrooms are legal/deregulated in parts of the US, including where I live, so it's less of a concern.
Today I have a prescription medicine that works. I'm cognizant of taking a single drug for too long. When I look up what I'm currently taking (sumatriptan) people online complain it stops working at 7 years of use. This is great, because now I feel comfortable taking it for 5 years before needing to switch. However, the second I start needing more to function, I'm switching it out. I do not want a life long resistance. That needs to be avoided at all cost. When I was taking the 4-aco I was a bit more cautious, because I can't find online how long it works for migraines. I would rather keep it in my back pocket if I ever need it again, so I went off it the second I found a prescription drug that worked, despite that the 4-aco worked better.
