Is this acute bronchitis?

Early last week, I woke up with a sore throat, it got progressively worse and then I had a cold aswell, the next few days, my voice was very hoarse and I had a persistant tickly cough. A few days ago after using a nasal decongestent, my cold cleared up, my voice is no longer hoarse and my cough is not as bad or frequent but I still cough more often than usual, I am currently using a honey and lemon medicine but it is having little effect. I am wondering if anyone has an idea of how long this cough will take to clear?
