First of all, thank you for service in answering questions. I have been experiencing this slimy saliva at the back of my throat. I feel it when I swallow. It sometimes causes me to have fits of cough, lasting a few minutes. It is sometimes so bad that I would vomit. This would happen at least once or twice per day. It sometimes wake me up during my sleep. I have gone to a doctor regarding this condition. I have been taking Zyrtec as well as drink plenty of fluid but nothing seems to help. I have to constantly take cough drops and chew gum.
