I've got this persistent cough and have had it for two weeks. I've tried everything and I've been up night coughing help me.
Could be sinus or allergies. Delsym makes a great cough suppressant, only take it at night to sleep. You want to cough during the day to ease congestion. If it continues see your doctor. It seems like bad coughs are common right now.
take a nap
Coat your feet in Vicks Vapor Rub and put on socks. The last time I had a cough, I slept like a baby!
