Nebulizer

I have only had my nebulizer a few days. Mucus was and is just coming to my mouth almost hourly. I have spit into many Kleenex boxes. My neighbor uses a nebulizer and has to leave after potlucks to have a treatment. Sounds like she is dying. Coughing up forever. I am still doing the Kleenex thing, have not been able to cough up much, like before machine. I am trying it like the doctor said. I will keep at it, all staff say it will help a lot.
