Thank you, Irene. I am going to see GI at the end of the month to see if I have GERD or acid reflux or silent reflux. Not sure the people you mentioned and yourself have mixed mucus with saliva. My late grandfather and my aunt produce around 8 ounces or more but always clear white. Mine is always yellow/green, glue like. Most people only produce foamy clear jelly like mucus, some mixed with a little bit of yellow plugs. (Please see picture from my sample amount that I sent for culture last week. ) That is the amount that I cough out after postural drainage almost every day. My right lungs hurt from coughing/ huff cough and from trying to get the mucus out.
