I've suffered migraines and sinus headaches for years. I was hesitant to try the oils even though I'd heard great things about them. Someone gave me thieves and peppermint one night when I had a migraine and I became an instant believer! I've never even had prescription medication that works faster than the oils when I have a headache. I went from taking medicine every day or every other day to 1 pill in the last month and the oils everyday!
