I love HTS. Many moons ago, perhaps even 20 years ago, before 7% became popular, I learned that even using the 0.9% when I felt congested was helpful. At the end of my neb treatments I'd just dump more saline in there and breathe it. Now that I have an Rx for the 7% I use it two or three times a day. The only time I find it hard to tolerate is when I'm very sick and needing IV antibiotics. But it doesn't stop me from using it. I just power through the treatment, coughing so hard it hurts, or worse yet, I puke.
