I joined the “7% club” 5 days ago. Here’s my experience: I was able to convince my GP to write a script because I gave her copies of the first page of two articles that Terri, Sue, and others have posted here, which she said she really appreciated: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4850692/pdf/13104_2016_Article_2054.pdf and https://www.resmedjournal.com/action/showPdf?pii=S0954-6111%2811%2900254-X
I’m using a Pari Vios Green LC Sprint nebulizer system. It’s been taking about 13-15 min to nebulize 4 ml of 7% saline. (I take about 6 slow in-and-out breaths per minute). I do cough sometimes during the process. The nebulizing has really helped me bring up mucus from my lungs. Until now, I’ve had mostly dry coughs (although I've gotten a bit more mucus in the mornings since I recently started taking 600 mg NAC). One thing I noticed is that when I nebulized sitting at a desk in a more confined space, the compressor pulled some of the nebulized fluid from the air and caused condensation in the tube from the compressor to the nebulizer. So, I suggest to new users to not be in a confined space when nebulizing.
