Hey, Im going through the exact same thing right now. I feel like I cannot get food all the way down my throat and and I keep hacking up little bits of food. There is a technical name for it that i dont remeber but it is related to stress and anxiety. I am constantly clearing the bottom of my throat for flem. It freaks me out and I am just waiting for it to pass. Thinking back, I have had something similar to this before and it went away too so no worries.
