@spider109 It took me awhile but at first I used to keep trying to clear mucus before bedtime and after some good conservations with my Chatbot I realized it is not necessary to get every little bit because you can do damage to your airway and make things worse. So now I do my saline and Aerobika twice during the day and get all I can and then let nighttime just come naturally and maybe a gentle huff or two to help it go.
