DoTERRA has already blended some great oils to help you. This is not only one of my favorite smelling oils, but one I use every night. I wouldn't be without it.
Essential Oil Blends
There are multiple uses when blending essential oils. Some are topical and a few can be taken internally. One of my favorite ways is aromatically, and my absolute favorite aromatic way is with a cool mist diffuser. There are other ways, including smelling straight from the bottle, placing a drop on your pillowcase, or putting some on a cottonball or tissue and placing it in your car or on your table. Try making room sprays mixed with water in a glass bottle so it's easy to access whenever you need.
