When Hurricane Maria hit us in 2017, we lost power for two weeks (we were
extremely lucky in that - we were among the first 4% of the island to regain power due to our proximity to a hospital).
During those two weeks, my entire lifestyle changed, obviously, so it's difficult to know what changed because of that, and what was just the fact that e.g. I went from sedentary tech work to nailing salvaged roof scrap on top of the house on our farm.
But - my blood pressure dropped. I lost weight. I did a lot of reading of books. My notes are more interesting for those two weeks because they were ink on paper and I could insert drawings and diagrams wherever I wanted. They were more thoughtful and less reactive.
I fixed a mosquito zapper by sheer force of will (the capacitor was shorting across a resistor - poor design, but once I figured it out I could fix it. I'm still using that zapper today, and only shorted the capacitor out across my finger three times. Ow.) That day, I was become death, destroyer of mosquitoes.
I guess I quasi-fixed the roof on the farm house by sheer force of will, too. Had to dig the nails out of the scrap - no hardware stores open. My son considers it a formative experience.
So I didn't choose to go cold turkey, and it was only a short time, and its lifechanging nature is impossible to tease away from concurrent events, but still - anecdotally, it's probably worthwhile to try it voluntarily.
