Get some cough syrup at your local pharmacy. It is all good unless you always get cough and keep on drinking the same medicine over & over, which in that case maybe there is something really wrong with you besides having just the cough.
is it dry cough? almonds are good for this. search for this on google for instructions on how to prepare it. if you don't have almonds, well there are always onions. yes onions are excellent for cough too! extract the juice from the onion and dilute it in water, add something to taste like a pinch of sugar or some honey.
