Oh and a cool mist humidifier. The heater running will just make you more stuffy but the humidifier will help with that!
All are good suggestions. I know Rubitussin and Tylenol are both considered safe. I would also try some tea w/ lemon and honey.
My doc recommended vicks vapor rub, Robitussin, tylenol, and hot herbal teas.
Take cough drops and ocean nasal spray :) both helped me
