You could use an essential oil, and douse the kleenex with it, just a thought. When I was pregnant, and would get stressed out, and even after, I would take those little plastic things that the hair dye gloves come in, put in some cotton balls, and saturate them with lavender oil, and take them out and just breathe them in to soothe me, put the cap back on, and slip it back into my purse. It worked wonders, and lasted for a long time.
