I was looking into it once upon a time, but I gained about 30 pounds and now my BMI is too high. I use a cpap and bipap machine, but I dont love it. I can tell the difference in my sleep quality tho. urrently set on 4/8 but I feel like it probably needs to be at 6/14. Initially the pressure was too high and I would wake up with inner ear problems and vertigo. Then they dialed it back a bit. I'd love to hear reviews on the inspire once you get it turned on!
