Headache Remedies

For some reason, I've been getting really bad headaches now and then lately.  I've tried several different remedies (cold compresses, Excedrin, naps, tea, etc.) but nothing seems to work too well.  I came across this headache oil from 21 drops.  I've never heard of them before, but they seem really awesome.  They make all kinds of therapeutic essential oils for anything from headaches and colds, to hangovers and PMS (I could probably get some use out of all of those!).  I'm very intrigued and I think I might just have to try their Headache Oil.
