So even though I dont feel as sick as I did on Monday and my throat doesnt hurt anymore, I still have a terrible cough. I've been lying awake since 10:00, coughing my head off. I already took Robitussin, but it doesnt seem to be working. I dont know what to do. I'd really like to sleep, but I would love to stop coughing more. Any suggestions of what I can do?
