I want to add I’m so not kidding that I cannot have a good quality of life without this machine. I was having severe memory issues and falling asleep at the wheel of my car even with 8+ hours of sleep. I would be driving and end up somewhere I didn’t mean to drive to. Commuting home i would sometimes need to pull to the side of the road and sleep. I’d wake up with headaches almost every day. One time I fell asleep on the floor of the office restroom while I was at work, or IN MEETINGS which is so embarrassing.
