Hi,I am a 63 year old female.After I have eaten,I develop thickened,sometime stringy,saliva.I have to clear my throat or cough to be able to talk.It seems to be sitting at the back of my throat.I have tried anti-histamines, Flonase nasal spray,Famotidine,omeprazole,and antacids.No problems are shown on examination of the stomach and esophagus.Thank you so much for your help
