@polokawsay: I literally make no commission off of this. I purchased the nasal dilator because I could notice I was getting out of breath and I have full range of motion in my torso and access to my diaphragm so I was thinking it had to be my nose. The left side of my nose during Pranayama I noticed was harder to get a big breath in so I'm testing out the nose dilator to see how big of a difference it makes during my workouts. I will be trying the sleep version tonight
