I don't smoke never did but my sinuses are often congested, more in the morning. It feels like I get excessive drainage and must cough-up phlem every, or most mornings to get my day started. What is it that might cause me to get congested at night and then have it drain and cause all this coughing in the morning? A Dr. put the little camera up my nose and down my throat she said she saw nothing abnormal but I had acid reflux take a OTC med don't eat before bed or drink alchol 3 hrs before bed as well. My singing voice has changed (can't hit high notes as high) I'm 47 yr old male over weight and under exercised
