I have post nasal drip from last 2 years. A thick liquid constantly comes in throat and I need spit it. If i swallow it then i feel like vomiting. Taken Lesuride OD75 for a month as suggsted by gastroenterologist but no effect. I also have acidity n vomiting problem. From past few yrs When I get cold my nose runs like hell n flow in throat also increases.the next day I vomit for entire day.cant eat anything. In vomiting there is very thick thing which feels difficult to vomit. Earlier this used to happen twice a year but from last six months this happened 4 times. Plz help. Unbearable
