to get rid of cough overnight put plenty of vicks vapor rub on your feet and add thick socks and sleep with the socks overnight. then drink a mug full of hot cocoa. elevate pillows,keep warm(this may sound crazy but sleep with absolutley NOOOOOO LIGHT.)You should fell better by the next day. (you may also cough a couple of times in the morning but that is just the extra mucus trying to come out so make sure you cough it out)
if anyone caught cough or flu it can be easily controlled.just add a small piece of Cinnamon stick in boiling tea or coffee.strain it and drink and u will feel nice taste as well as the relief from disease.
