I know we all come from different parts of the world and in different time zones. I live in Central Time Zone. How many night owls are there? I worked night shift 30 years. I never thought it would affect my sleep pattern once I retired. I was wrong. If I go to bed at a decent hour (9pm-10pm), I'm up by 2am and my nights shot. Anyone else have that problem? The good news is it's quiet and you have time to think.
