There are also the triptan class of drugs such as Relpax. The problem is you have to go to a doctor to get a prescription. Doctor visits are expensive (relative to my income for most of my life) unless you have access to a school clinic or you have insurance. Migraine medicines should be OTC. The side effects don't warrant limited access.
There is a cheap (prescription) drug called ergotamine that tickles brain receptors similar to those affected by LSD.
