Drink before bed or when you are just relaxing. With a cold you have to treat the symptoms. If your coughing suck cough drops to prevent a sore throat. Its important to get the appropriate kind of cold medicine.

Wear heavy clothes to promote heavier sweating. Running the shower or bath on hot is a good way to open up congested areas.
