There are so many different combinations of essential oils that can be used to help you achieve the result you are looking for.
Although most of these are intended for a diffuser, feel free to make a mixer in a roller-ball bottle, too. You will still get your desired outcome.
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.
