After having sleep study done and bought an airsense 10 with the latest nasal pillow (very very comfortable, i slept like a log the first day I used it). Initially, I felt somewhat different/better but it was not totally obvious until i slept over at cousin's house without the machine and felt wrecked the next day. I then realised my coffee intake was half of what i usually have and I don't yawn during the day as much!
