Post nasalšŸ¤§

Any of you guys have post nasal drip? I need help without having to cough so much because mucus trickles Down at the back of my throat and then I have a coughing fit so itā€™s embarrassing, I drink water but it doesnā€™t help

I literally look like Iā€™m dying with my coughing fits ! I do blow out my nose cause I am sick but even with that itā€™s useless, any tips ?
