I noticed you said you were on HTS, pulmozyme, advair, etc. but you did not mention any inhaled antibiotic. I you feel like you're coughing up a ton you might want to see if there are any inhaled antibiotics you could try. If you culture PA you could try tobi, cayston, or even collisten(sp?) I know if I'm NOT on an inhaled antibiotic I feel like crap. They might be a bit easier on your body as far as side effects go. Good luck.
