I have a cough too but mine is asthma/smoking. I know the two together dont' really mix but oh well. I am going to my doc tomorrow to hopefully get on some antibiotics and get some better cough syrup as I think I've got bronchitis again. I get it quite often as I have scar tissue in my lungs from a suicide attempt.
I hope your cough goes away soon and I'll pass you some Tussin DM.
