for the last 3 or 4 nights now, when i lay down it feels like i have something stuck in my throat (like a thick piece of gum). i’ve tried throwing whatever it is up but that’s not working. i’ve drunk sprite that’s not working. i’m starting to become miserable because i can’t get what it is out. it feels like i have to throw up but it won’t come out, it’s like right at the top of my throat. help what can i do?
