you can hock it up and spit it out (assuming you are man since women seem to have a near-universal objection to doing this). you can melt it down and reduce the mucous viscosity by hydration (drinking lots of water) saline nasal sprays or increased humidity (humidifier vaporizer or hot showers). medication wise you can take a decongestant during the day (not a night) such as sudafed a mucolytic (mucous-thinning medication) such as mucinex. an antihistamine at bedtime can temporarily dry of the river of mucous so you can sleep better. this is assuming however that you are medically able to take these types of drugs. sleep with your head elevated and hang in there. assuming you do not have a sinus infection this should clear up in less than a week.
