David D. ★★★★★ Five days in and very happy! I have sleep apnea and nightly use a full mask CPAP device. I am able to see my sleep results the following day. One of the measurements reported is events (apneas and hypopneas) per hour. These have reduced substantially. Prior to SleepQ+ and in spite of the full mask I would still awake during the night to a dry mouth which I believe was a signal that some mouth breathing was still occurring. No more dry mouth!
