After 15 years using a CPAP for OSA, I stopped using the machine about a year ago. I was only able to use it for 3 to 4 hours per night as other conditions caused me to wake up and I couldn’t get back to sleep using the CPAP – way to uncomfortable. I took matters into my own hands (please don’t judge) and using my Tracker, which records sleep activity and heart beats plus occasionally a oximeter, I am able to record and analyze my sleep to see if I am having any OSA events during sleep. Due to osteoarthritis, Spondylithosis at L4, and fibromyalgia, I cannot sleep longer than 4 or 5 hours per night. Since I have been retired for 4 years, I am able to spend 3 hours actively involved in reading the newspaper, watching TV news, surfing the web, and writing. I then return to bed to sleep another 2 to 3 hours so that I average 7 to 8 hours of sleep. I have trained my body to sleep on my right side and rarely move from this position. I wake after sleep in the same position. This, I believe, reduces the possibility of an OSA sleep event that would occur if I slept on my back. The 2 phase sleep was quite common in the days before electricity and the light bulb. We have gotten away from it because we can stay awake longer involved in activities using light. I have found that I feel more refreshed after my second sleep and am good to go for 12 to 14 hours in the day. The only drawback is if there is another person in the family who sleeps late and is awake during my second sleep session. However, a routine can be created that works for everyone. Just don’t expect to see me out and about until after 12 noon.
