I had a septoplasty and a non-cosmetic rhinoplasty, but it didn't cure all my problems.
It's something that definitely helps me. I'm still taking in air, but am exhaling for twice the amount of time as I am inhaling.
I'm unsure if it works for everyone, or if there's a real tangible benefit, but I feel a definite ease when I do it.
