Can't kick this cold 😷

My husband and I went to the beach with my family around the middle of July. Towards the end of our trip, I came down with a nasty cold...sore throat, fever, runny nose, etc. Around 3-4 days after that I developed severe laryngitis and a nasty cough from the cold that lasted 2 days. Since then I have had no fever or a sore throat but I have been sneezing, had a nasty cough and runny nose. When I cough I am coughing up mucous..it's not a dry cough. I have tried NyQuil and Mucinex extra strength. It was getting better until we went to the beach last week with my hubby's family. Now the congestion and coughing is back in nearly full force. It's going on 3 weeks now. Heeeeellllp!!
