The first night with the CPAP was okay, except for when I inexplicably started breathing through my mouth around 4am. Air was still being sent to my nose, which dried things out rather quickly and made me sneeze violently. Although I was a bit brighter-eyed upon waking, I still felt drowsy during the commute. I'm told it will take some time to become accustomed to the apparatus. It's worth a shot I suppose.
