I started using essential oils to make up a rub for my sore knees (injury now passed) then progressed to using them in a burner for nice smells in the wintertime. I've found if I use peppermint oil in the burner it feels as if I've just eaten something pepperminty rather than making me want to eat something pepperminty. I get the same feeling (to a lesser extent) with orange oil but not with anything else I've tried in the burner. The other night I had the munchies big time so I put the peppermint oil into the burner and I was OK and managed not to raid the fridge for a wedge of cheese.
