Sometimes a cough is caused by a dry throat after eating. To avoid this, sip water or warm tea to keep the throat moist, and thus perhaps lessen the severity of the cough. Some find that hot tea with lemon or honey is even more soothing – but always keep in mind to never drink something you might have an allergy to.
