What is the strongest cough medicine without codeine?

If it is a dry cough ( no mucus, just scratching of your throat ) Than just fluids and cough drops ( it stays closer to your throat and will relieve it)

If there is mucus in your chest, try a hot shower to open up it up and lots of water and, if it's Allergies, benadryl . If not than some DayQuil..

PLENTY OF SLEEP

Hope this helps, Does for me. (:
