whenever I lie down on the bed I got coughing what is the best cough syrup in 5th months

A. If you experience coughing while lying down, it could be due to postnasal drip, acid reflux, or a respiratory infection. Try drinking warm water, using steam inhalation, or keeping your head slightly elevated while sleeping. For a persistent cough, cough syrups like Benadryl, Ascoril, or Chericof (depending on whether it's dry or wet cough) may help, but it’s important to consult a doctor before taking any medication, especially since you’ve had this issue for five months. If the cough is severe, worsens at night, or is accompanied by wheezing or breathlessness, seek medical advice promptly.
