I’ve been diffusing my oils for only a month now and I can honestly say I feel a HUGE difference. I wish I hadn’t waited so long to get my diffuser, but I had to save for it. The wait was totally worth it! When we’re feeling a little cold coming our way, I diffuse 3 drops of Breathe and 3 drops of OnGuard. In the mornings I’ve been using Peppermint and Lemon. What a way to wake up! Or Wild Orange and Lemon. What do you diffuse?
