From The Long Lost Friend:
Tame thou flesh and bone, like Christ in Paradise; and who will assist thee, this I tell thee [name] for your repentance sake. + + + This you must say three times, each time lasting for three minutes, and your headache will soon cease. But if your headache is caused by strong drink, or otherwise will not leave you soon, then you must repeat those words every minute. This, however, is not often necessary in regard to headache.
