In the vast majority of cases for my family, Dextromethorphan is a miracle drug. We're in the middle of cold and allergy season here, and my kids (and I) stop coughing within 5-10 minutes of taking an appropriate dose. Once every 3-4 years I'll get a cough so bad that DXM won't fix, and when that happens my doc gives me a prescription for a codeine based cough syrup that fixes it (and renders me useless as a human being).
