Shower Soothers. I don't know if they've been discontinued, but I can't find them anywhere around me.
They were these little things you put in the floor of your shower that released strong decongestant aromas when hit with warm water. It was the best remedy for a really stuffy nose!
Not exactly the same, but we used this when our babies had colds. It smelled like Vick's Vapo-Rub. It might help!
