I've gone through not one but two turbinate reduction surgeries myself. One when I was young and another several years ago. Alas, my quality of breathing now is still pretty abysmal. It's just gotten to the point where I've come to accept having to breathe through just one nostril all the time, as much as a nuisance it is. Frustrating to have spent all that energy and funds to land back at square one.
Also went and tried CPAP for a while, which didn't really help me with breathing for restful sleep.
Where I notice this most is probably during heavy exercise. Having to breathe through the mouth during intense aerobic exercise makes me hit my limit much faster.
