What seems to work well for getting me back to sleep at 4-am is to listen to "Lisa P Hikes day 1-190" ...... You Tube video ..... 190 different videos from March to October, 2021 with 41-year old Lisa Parker ..... aka "Tex" ...... hiking the entire Appalachian Trail from Georgia to Maine, alone by herself with a smart phone self-video held on a walking pole while she is walking.
It makes me feel like I am along with Lisa P. for the hike, going the 2200-mile distance.
I turn the laptop around backwards and just listen to the audio, and usually fall asleep!
To find it, Google: "Lisa P Hikes - Day 1" and I wake up feeling like I've just hiked 18-miles or so, somewhere in Rock-sylvania ......aka Pennsylvania, or somewhere. ....
