Annick Goutal's Eau d'Hadrien refreshes yet balances my mood. Something about the mix of lemon and the woodsy base, which smells very natural. I also enjoy a green cedar oil for the same effect.
I've been finding musk fragrances soothing lately, too, especially certain white musk fragrances and even laundry musks. I never cared for those before, but I do enjoy them now. They just put me at peace for some reason.
Neroli & orange blossom induce a sublime serenity. Jasmine, which used to, no longer does. It now makes me feel queasy. Hormones! :-/
