I cough a lot at night, despite taking syrup and even using a pump (Alvesco). I have to sleep sitting up. What should I do?

In this situation, it is likely that the excessive coughing at night is caused by the buildup of mucus in your throat. You can try using a product like Sinus Rinse™ twice a day for at least 5 to 7 days to reduce the amount of mucus in your nose. This may help lessen the mucus dripping into your throat while you are lying down, allowing you to finally get a good night's sleep.
