One thing I did notice, though, was that inside of a day, I was up with the sun and ready to sleep within an hour of dark. Right back to a natural rhythm without electric lights.
That sounds like a good time. Though 700 miles, I hope at least horses were involved...
I am the same way - I have all kinds of trouble with my artificial environment... I have to remember to turn lights off at 9 pm or I will just keep going - I don't know it's dark. My last alarm is at 11pm which tells me to shut off everything, put on the kettle, and go out on the porch with my tea. Half an hour and I can feel that rhythm.
Same with morning. Inside my cave, with the windows shut all winter, I don't know the dawn. Terrible trouble getting up... groggy, grumpy... takes an hour or two to shake my giggles out.
But put me under the stars in a tarp shelter and I am up like a shot the minute the birds start squeaking half an hour before sunrise... Wide awake in an instant, and ready.
Yep. I know that rhythm thing. I feel it in my very bones. I am not made for time.
