I have and they did help some. I have used one called Deep Blue and I really liked it. I also use lavender and peppermint for nausea, relaxation. A friend of mine sells a different brand and apparently they have something similar that I am going to try as well.
Deep Blue is amazing! You can get it as an oil or as a rub lotion!
I use lavender sometimes for stress and it seems to work.
