Sticky mucus on the back of my throat, cannot get rid of it. Please help.

In the past three years I have thick mucus on my throat. Drives me crazy. It makes me feel like I am suffocating. I went to the doctor several times. I was told that I have acid reflux and that irritates the lining of my nose which produces a sort of post nasal drip, which is constantly dripping in the back of my throat. I have taken different acid reducer medications and the situation improved a little. However I started to gain weight so I stopped taking meds. Does anybody have similar symptoms? It feels like when you have cold and you have that slime on your throat what you want to constantly swallow to get rid of it. Except this sticky thing does not move! 2 years ago I started to use kleenex to simply wipe it of, sometimes works. This sticky thing bothers me so much! Please if you have any advice what would work in my case let me know. Thanks
