My mom and dad both use one. My mom uses the nasal pillow and my dad uses the nostril one. I have tried both and if I ever have to use one I will definitely be using the pillow. Took my mom about a week to adjust. My dad had that surgery back in the early 90's and it did nothing to help his sleep apnea. He said that was the worst experience of his life. And my dad has a very high pain tolerance. I remember how bad he looked in the hospital. I know that they both feel much better now that they have their machines. Get the right one though. My dad had to recently get a different one because his old one didn't do the job right.If you can use a nasal pillow do it. It is a little more comfortable.
