My wife scheduled me for a sleep study, and when I went they woke me after an hour and told me I had 41 sleep interruptions in the first hour of monitoring. They fitted a CPAP, and I woke up more refreshed after the sleep study than I had in a long time. Got the CPAP, it works like a dream, I sleep really well now every night. FTR, I'm not obese (6', 195#). I bought a new CPAP for home, it cost < $500, and worth every penny.
Sleep apnea is very serious, consistently getting < 6 hours of sleep has a strong correlation to heart disease and dementia when you get older.
