I've tried a large amount of conventional and alternative remedies, and for a headaches I would choose a coffee enema followed by an epson salt bath. Before I discovered this, I used to take from 4 to 6 strong analgesics in one day. The coffee enema causes a bile discharge that allows the liver purify more blood. I know I'm not able to explain it properly, but I promise it works. It is not toxic, unlike the drunk coffee.The epson salt bath is accesory, the coffee enema works on its own.
