The only thing I've found that really worked was zinc tablets (3) taken on a FULL stomach (or else they make you feel nauseated). This even works with the flu. For a cold, like you describe, also eat some hot broth spiced with cayenne or hot sauce for the sore throat (should make your eyes water and your nose run). Finally, a hot shower and then go to bed, wrapped up warm. Stay completely warm and in bed until you feel better. The earlier you do this, the better it works.
