Dug around and found that this is a commonly reported side benefit of a ketogenic diet.
Sounds off the wall until you realize Keto diets were originally used for managing childhood epilepsy.
Injections are nothing compared to two failed neurostimulators. Yeah, it's a niche drug, but there's plenty of space for those.
LSD doesn't "cure" migraines, there will never be a trial. It will stop migraines, but so will triptans, and you know, without the side-effect of wiggin' nuts.
Oddly, along with three prophylactic meds, I seem to be able to abort migraines with 1/4 tsp ginger powder dissolved in a cup of water. I doubt the ginger would help without everything else though.
The worst part: you pretty much have to pay a $1000 tax if you present at the ER with a migraine, because they will not believe you. People will be in a rush, they will not examine the giant history in the EHR spanning years and years, and you will be likely be suspected of drug seeking. So you have to say yes. $250 for a useless injection of sumatriptan and $750 for an hour of continuing to lie in pain on a bed until they hopefully realize you're telling the truth.
I have taken intranasal capsaicin to try to stop the pain because a paper on the internet said it might work. It didn't even hurt. I'll repeat that: I snorted the active ingredient in habaneros and pepper spray and didn't even feel it because it was so far overshadowed by the pain in my skull.
