I was diagnosed with OSA in 2009. My sleep doctor at BWH thought it was perhaps due to gaining alot of weight over the previous 4 years. I used a CPAP machine for two years and then discovered Provent Therapy. The very positive is that they work wonderfully and only involve a small sticker-like circle that you put over your two nostrils. They each have a small vent in them. i sleep soundly and wake up like I used to (before having OSA). The very negative thing about them is that insurance doesn't cover them and they aren't cheap. But they allow me to go camping, traveling, etc. without my CPAP machine and allow me more comfort and intimacy with my husband. I use my health reimbursement account that i have at work to cover their cost. I noticed on the surveys that Provent was not one of the options. Perhaps it could get added. I look forward to reading more on this website.
