That's exactly the situation I'm in - family of 10, and only 2 of us over 18. I guess we'll have to use Vick's Vapo-rub, or inhale oil of menthol. Unless that's regulated, too ...
Vick's Vapo-rub...gives me the willies just to think about that stuff! The plus for sudafed is that you don't smell so bad when you walk out the door!
