Back to Nights
Well, it's been a nice (but all too brief) opportunity to revisit the "normal" circadian schedule, but it's back to work tomorrow night. I've had a string of 9 days off, during which time I have completely reversed my usual sleep schedule. I've fallen asleep by 10 or 11 pm every night and awakened by 5 am each morning. The first few days were tough, requiring a couple of naps at odd times here and there, but lately I have slept only once per 24 hours.
It has been wonderful to actually feel awake and mentally sharp during the afternoon hours, something I always had difficulty with on my shorter strings of off days. And it's weird to not be wide awake at 2-3 am, eating a late dinner and tiptoeing around the house.
The first night shift back is going to be difficult, I imagine. Here is some interesting information about shift work sleep disorder.
