What can I take for bronchitis?

I got sick 2 days ago, and then this morning, the cough started, and my chest hurt everytime i would cough. So, I am pretty sure I have bronchitis. WHat things can I take for this? If I have another day of this I am going to go to the doctors. So tomorrow I will make an apt. But I know they cant help me with a common cold or anything. and thats what I have. if anyone could help me with what I should take, that would be great. Thanks.
