Maybe postnasal drip: Mild nasal allergies can cause some muscus dripping in back of throat/mouth and collects there during sleep and can turn a bit brown in the am. During day, little mucus/drip is pulled down by gravity, but when sleeping mucus tends to stay in back of throat and thus productive coughing/coughing in the early am. If worsens, call doc for eval. Good luck.
