I've never woken up at 2am and felt super rested no matter what time I went to bed.....
I've been dealing with insomnia for over 35 years. I've had every type of sleep aid prescribed to me over the years. All have caused more problems than they solved. My entire working career has been based on, "early to bed, and early to rise". I would come home around 6:00 PM, exhausted from 11 and 12 hour overtime workdays.
Shower, eat, and back to bed because I couldn't keep my eyes open past 7:00 PM. Rinse and repeat. When I retired that took away the exhausted part. I would still find myself tired and going to bed early, only to wake up at midnight starring at the ceiling fan. I couldn't go back to sleep to save my life.
I mentioned this to my doctor, and he said, you're retired now, that's a big part of your problem. You're not "draining your batteries" like you used to. Just stop trying to conform to a schedule you had when you were working.
When you are tired, lay down and take a nap. When your awake, get up and do what you normally would do. What difference does the clock make?
Why are you trying to keep the same schedule when you don't have to? He was 100% right. I started doing exactly that, and I was feeling much better within a week. My hours are wacky, but what the hell do I care? Sometimes I'm up at 10:00 PM until 3:00 or 4:00 AM.
Then I'll lay down if I get tired, and sleep until I wake up. As long as the total amount of sleep you get meets the requirements of your body, when it needs it, why try to control the hours if you don't have to?
I've talked to a lot of retired guys and they are doing much the same. My wife is doing much the same, but not quite as off schedule as I do. Our master bedroom is at one end of the house. So it doesn't create a problem with sound. If I watch TV, I'll go out in the garage. It may be strange, but it works, and that's the main thing.
Bottom line....... If you're able to, don't be afraid to change your lifestyle to suit your sleep requirements. You'll feel a hell of a lot better.
