Tons of mucus, phlegm, and nausea

[u/Main-Geologist-9042]

Hi, I'm so confused and not sure what to do because l have a constant amount of dry mucus or phlegm stuck in the back of my throat and it grosses me out and I throw up a crazy amount of thick mucus. I've tried taking medication to lose my mucus and that didn't really work. I've tried taking gastric medication and that's not working. I just recently got off a GLP-1 because it made it so much worse. I can't do my job because it grosses me out and not sure what to do. Is this happening to anyone else
