There is a small core of us that post at this time everyday. I worked a midnight shift for over 30 years until I retired 4 years ago, and have never established or gone back to a normal sleep pattern of going to bed at 10 and sleeping through until 6. When I did work the shift, it seems I ended up sleeping twice during the day, maybe an average of 2-3 hours each time. There was never a time I slept all the way through. Since retiring, the night goes something like this. I can hardly keep my eyes open by 8, then am wide awake by 1 am. Sometimes, finally around 4 am, I go back to sleep for a couple of hours until time to get up for work. So this is why I post at this time. What about the rest of you, why are you up at this hour? In addition, any ideas of how to learn to sleep all night would be appreciated. I am not going to start the sleeping pill routine or hook myself up to a machine. I had rather keep this pattern. Thanks for your response.
