Try. Cough 2nd to posterior drip of mucus. Difficult to treat. Vasoconstrictors with antihistamines : allegra-d, claritin-d;nasal sprays like nasal saline or afrin; cortisone sprays: flonase, Nasonex (mometasone) or others. Also breath a vaporizer with the vicks. Guaifenesin may help to fluidify the phlegm. Some meds cause cough 2 (lisinopril, Enalapril captopril:ace inhibitors).Sleep sitting.
Could use more info. Cough and throat symptoms that occur when laying down are often due to "silent" or "atypical" reflux. This means that fluid from your stomach comes up into your throat without feeling heartburn or discomfort. This can cause significant throat symptoms including hoarseness postnasal drip and cough. Elevating your body and not eating or drinking for three hours before laying down can help.
Night time cough. Depends. There are several possibilities. Perhaps you are allergic to something in your bedroom that causes a reaction at bedtime or asthmatic bronchospasm. Another possibility is that you may have acid reflux (gerd) from your stomach into your throat causing irritation when you lay down through the night. See your physician for an examination to determine the cause.
