I have a really bad cough and its been the third day.i'm allergic to dextromethorphan and can't see my doctor for three days.i cant sleep.please help!

Don't over suppress: Cough is your body trying to protect itself so it's hard to answer without an exam. Stay hydrated, try green tea with honey and maybe a little whiskey at bed time if you like. Should also gargle with antibacterial mouthwash several times a day, and may want to try Emergency Immune Boost during the day. Do you have earache or sinus issues? May want to sleep with humidifier but make sure it's clea.
