Post-nasal drip?...: This could be related to post-nasal drip. When you lie down, the mucous from your nose and sinuses can drip into your throat and then you cough this up. If you have other symptoms like fever, shortness of breath, wheezing, etc., then you should definitely see a doctor to rule out infection. If this persists, see your doctor for evaluation/treatment.
