@becleartoday Your: "or breathing more shallowly" made me think of how important it is. I finally learned to do, to do deep breaths in to hopefully get the saline deep down into the lungs. Deep breaths, hold and from what I understand we are to slowly breathe out with some resistance as you breath out...as if blowing on a whistle.
Does that last part sound right.....resistance..... as if blowing on a whistle???
