Jelly like substance on a deep cough comes up. There is spit in the morning that contains dark brown/black specs in spit. Slightly thicker than spit. I'm 23 ex smoker, pretty heavy for about five years have recently quit 60+days ago because of this reason but it still remains. I have acid reflux but mange pretty well. Cant figure out what this but often is so thick in the morning that it makes me vomit.
