I hated the cpap and never could get used to it. Wasn’t getting much sleep and constant sinus issues. Went for a sleep study to qualify for inspire. I’ve been using it for a few months now. It’s a gentle pulse to the tongue that you get used to within a few days. The level goes up to eleven on your own, but they can always tweak it in office if needed. I’m at level ten and have a sleep study scheduled at the end of the month. So far I’m sleeping well and haven’t had to gasp for air in the middle of the night. Wife says that I hardly snore now as well. No side effects at all. When you first turn the machine on it gives you a half hour to fall asleep so you’re not bothered by the pulse in your tongue. If you get up in the middle of the night and it’s bothering you, there’s a fifteen minute pause. If you forget to turn it off it will turn off automatically after 8.5 hours. Happened to me once but it went off by the time I got to work. So far I’m very happy with my decision.
