I'm Currently In The Waiting Room At The Urgent Care.

I'm currently in the waiting room at the urgent care. My mom was in town visiting and had bronchitis and now I have the same symptoms. Prior to them coming I had a sinus infection and now I have a horrible dry cough, especially at night and I find it very hard to breathe. My son has asthma and I used his alnutetol a couple times at night when I could not stop coughing. I'm miserable bcuz I can't sleep as I am up ALL night coughing. My mom was prescribed some cough syrup with Hydro condone this afternoon and said it's the only thing that helped her sleep through the night. Is that the best thing for this kind of situation? I can't go another night without sleep. I work full time and I'm a mother. I'm miserable. Help!!
