In some ways, it was just incredible. I got to take my kid to a water park until 1pm on a weekday and never once wondered what I was missing at the office. I got to drink Bloody Mary's for brunch on a Wednesday. I got to take a nap (!). At night, I didn't have to go through a list of clients I was working on that day to think about who would come back with their hair on fire the next morning. I slept. A lot. I stared into the Caribbean Sea. A lot. It was great.
This is usually how the hostages behave for a few months after the police free them from the kidnappers.
But seriously, your body is recovering from chronic fatigue. You'll go through a few months of adjusting physically & emotionally as well as mentally. The sooner you get on an exercise routine (and limit the drinking/food routines) the better.
After nine years of ER I still try to take a daily nap, preferably 30-60 minutes. There are a few days when I'm too wired to nap, and a few days when I'm too exhausted to sleep less than two hours. But I hate powering through 16 consecutive hours of wakefulness, caffeinated or not, and I try to avoid it whenever possible. Everyone
else is much more pleasant to be around when I limit
my awake time to eight hours.
By the way, if you're going to stare into the Caribbean then you might want to consider surfing lessons. Or at least a stand-up paddleboard.
But at the same time, it's a little disorienting. It's Friday night and it feels like....uh....I'm not sure. What day is it again? Do I work tomorrow? Did I work today? I'm sure this will fade with time, but I'm almost nervous as hell because I can't figure out why I'm not nervous about something. Does this happen to everyone?
No more Sunday Night Syndrome, and no more Thank Goodness It's Friday! Instead you'll celebrate "Thank Goodness It's Monday", when all the workers get off the roads and out of the public spaces, go back to their cubicles, and leave the rest of the world free for you to go out again.
We regularly lose track of what day it is. As in "I need to look at a calendar" lose track. Some people use a dayclock, others have set routines. I try to shave every Mon & Thu, and we try to have pizza dinner every Thu. We also try to work out every Sun, Tue, & Thu morning and I try to do taekwondo on Mon & Wed. Tue is trash day, Fri is either recycle or green waste. And so on.
You'll adjust. Relax and enjoy the process, and try not to worry about the results!
