I had the stuff after treatment Eileen mentions but it stopped in about 2 months. I now have constant coughing and never know when the goo comes with the cough but it is small amounts with black and green globules embedded within. It is very salty. I feel like I need to cough up more but the coughs are usually dry. I drink about a gallon of water a day and if I get too dry, the goo gets more voluminous.
Eileen:
You may remember my old song sung to the tune of Crystal Gale's "Don't it Make Your Brown Eyes Blue" but it was more of a "Don't it Make Your Brown Goo Clear". Once it turns clear after treatment, you have officially weathered the huge ropes as you so accurately describe!
