" Question I believe I suffer from &amp;#039;post nasal drip&amp;#039;. I constantly have to spit into a tissue throughout the day.  At mealtimes I usually have to spit a dozen times to avoid swallowing a thick, clear mucus. Often I involuntarily regurgitate food and even drinks (including water).  Half a pint of mucus or more (with food and drinks suspended in it) will suddenly erupt from my stomach halfway through a meal. This happens at least twice a week.  The medication that I am presently taking, Clarityn and Flixonase are reducing my symptoms by about 20 per cent.  I would be grateful if you can help.   Answer Post-nasal drip is a common and troublesome symptom, but it does not normally give rise to such severe symptoms as you describe.  Post-nasal drip refers to the production of naturally-occurring mucus from the nasal passages in a greater than normal quantity.  The mucus slowly slides down the back of the throat and in to the stomach where it is digested.  Particularly after a cold, the mucus can become more catarrhal and thick and gives rise to the feeling of a lump in the throat, or a feeling of continually wanting to clear the throat.  Although a nuisance, the mucus is usually of an insufficient quantity to cause vomiting and I feel that this is a symptom which should be brought to your GP&amp;#039;s attention.  It may be that your constant spitting means that you are swallowing air, and this can cause sudden painless vomiting.  Also, the more you spit, the more your salivary glands will compensate by producing saliva and this may be creating a vicious circle of over-production. I suggest a programme of gradually trying to spit less and less. This should allow the salivary glands to return to a more normal level of production.  This should be reflected in a considerable improvement in your symptoms.
