Teri, I also keep a small container of garbage by my bed, although I very rarely require it. Basically, the only times now that I cough up mucus is when I do my treatments, and occasionally when I am working. But I went through a very rough patch when I was in my mid 20s where, I lived in a room with paneling on the walls. The panels were fashioned out of formaldehyde, which is embalming fluid. I constantly coughed up mucus, was on antibiotics every other month or so, and hospitalized once a year. I actually thought my CF was progressing so much that it was near the end. So many nights of insomnia, and staring at myself in the mirror so sickly, coughing. I was choking on my mucus, it felt as if a python were squeezing my throat. I finally had enough and rectified that by tearing all the paneling down and finding out there's warning stickers on the back of them that say that they *may* cause harm to people with upper respiratory problems. I remodeled my entire room and I am perfectly fine now.
The moral of that little story is even though things may seem real bad, most likely if you stop and analyze your situation, there is an answer. Good luck to you Teri.
