I have a productive cough, and i can't sleep. i was wondering of there is any home remedies to cure fast.?

Productive cough: The value of productive coughing is the clearing of unwanted materials from the respiratory tract. Curing it beneficially would be by alleviating the primary cause. If this is viral, it should clear up by itself. If you smoke, stop. You can suppress cough with a variety of compounds containing dextromethorphan, but this will also inhibit clearing of materials that may be beneficial.
