Hello!

I am 24 and i am experiencing an issue from the past 3-4 years whenever i eat or i get up in the morning my throat is usually full of thick oily sort of mucus and i have to cough hard to clear my throat and sometime excessive coughing causes sensation of vomiting.

I will be grateful if anybody could tell me a possible solution to this problem
