I used to be such a night owl. Worked 3p-11p for years, loved it. I'd go to bed around 2am. get up by 11am.
Over the past 5 or 6 years, I somehow switched.
Yes, I got a day job, but I don't find it tortuous to be up early anymore. Weekdays I'm usually in bed between 10pm - 11:30pm (depending on what's on TV
) I try to get up by 7am so I can work out before work, but that only actually happens about once a week. It's usually 7:30 or so.
Weekends are hit & miss. If I'm at home doing nothing, I can easily pass out by 10pm. If I'm out & about or drinking, I can easily stay up until 3am. Either way, I'm good on 7.5-8.5 hours of sleep. More or less & I feel like crap.
