I had a sleep study done 20 years ago. If I recall correctly, I "woke up" 15 times every minutes. I was given several different machines to try for about a month, but I could not sleep with thing strapped to my face. I chose to go with the surgery. I was supposed to go back every 5 years for the sleep study, but didn't, because my wife had not complaining about my snoring or lack thereof. The doctor told me that as I am getting older and likely getting fatter, there would be more fatty tissues around inside my throat that would block my air pipe.
Before finding out about my apnea, I was always tired. I thought it was because of having 3 little kids. I was taking actuarial exams and having difficult times passing them because I could not remember what I read. I felt much better after the surgery and finished all my actuarial exams within several years.
Iam very happy with the surgery decision, even thought I was living with only Ensure for the first 3 weeks after the surgery.
