Hi Leah,we're kind of in this together then. I'm trying the same routine as you, two inhaled and two oral doses daily. The nebs so far haven't been an issue because I mix the gsh with the hypertonic saline, a.m. and p.m.. Soon I begin my tobi cycle, which will add at least :15 to the whole treatment. Right now the bigger issue for me is the cost...I weigh about 190lbs, which works out to a total daily dose of 5600mgs. I'm only two weeks into the routine with really nothing significant to report. I'm hopeful for positive results.
