as silly as this sounds, rubbing VICKS or BENGAY or ICY HOT on the bottom of one's feet and then putting on thick socks, prevents coughing while in bed. now, SNOPES says it is untrue, but when we had colds after christmas we tried it and it worked.
a lady we play cards with is troubled by a cough at night and she tried it last week and was shocked as it worked.
WHY DOES IT WORK?
