Mild Apnea - Night 2 CPAP... holy crap.
Discombobulated rant ahead: Is this what it feels like to wake up refreshed? My OSI score was only something like 10.5 before, pretty mild.
I only decided to succumb and finally try a cpap because my sleep had gotten progressively worse since a brief bout of illness recently. Two months of heavily fragmented sleep. Worsening anxiety, and night time wake-ups with high heart rate.
After 2 nights with a cpap, it's like a switch flipped and suddenly I'm awake and my nervous energy is just... subsided. I had very low expectations but holy crap I feel so much better.
