Here's the ni:dr (not interested, didn't read) version: biphasic sleep appears to be for me.

A month ago I promised you an update on this today (see the last paragraph of the linked post from June 15th).

If you didn't see that post and don't want to go back and read it, biphasic sleep is sleeping in two shifts with an interval of wakefulness in between. It was most likely the common mode of sleeping in Europe before the Industrial Revolution, and it was probably the ordinary mode of sleeping in colonial America. Thomas Jefferson and Ben Franklin are said to have slept that way. It was killed by electric lights and by the modern custom of commuting back and forth to a workplace away from home. I'd give you some links, but you know how to use Google if you want to know more.

The results
It's been a somewhat rocky month, but the upshot is encouraging and positive. I slept all but three days "biphasically" this past month. I had to experiment with several schedule changes, and I had to suffer several failures. Nothing big; just ordinary self-indulgent failures. One time I took a late afternoon nap that messed everything up. One time I stayed up too late watching tennis matches (it was an eventful Wimbledon). One time I couldn't stop writing on time and got to bed for Phase II way too late. And one time I just couldn't get to sleep for Phase II. Three times I said the heck with it and slept the old way. Or tried to.

However I really like the schedule overall. It solves two relatively large problems in my life: how to get an adequate amount of sleep, and when to find time in the day for uninterrupted long-form writing.   

The current schedule
Here's where I've ended up so far:

I set (gentle) alarms for 10:00 p.m., 2:00 a.m., 5:00 a.m., and 10 a.m. I try to get in bed after the first alarm between 10:00 and 10:30 p.m. and turn my lights off by 11:00 at the latest. I sleep for 3+ hours; get up at 2:00 a.m. and come downstairs, where I have the office prepared with a yellow light bulb in the table lamp and the yellow "Night Mode" color cast on the computer display turned all the way up; write for three hours; and then go back to bed at 5:00 for another five hours. Then get up at the last alarm at 10:00 a.m.

I don't cope well with alarms, because my worrying brain wakes me up before the alarm goes off—sometimes an absurdly long time before the alarm goes off. But I'm telling myself every night to just sleep till the alarm, trust the alarm, etc., and I'm getting used to doing that. Perhaps counterintuitively, I have had little problem with waking and going to sleep. I get up at 2:00 feeling perfectly refreshed and ready t0 go, and if I'm just patient with myself I can get back to sleep at 5:00 with relatively little trouble. I have various mental tricks that help.

I should add that I've had sleep problems literally my whole life. I only napped till I was barely two (source: Mom, although I have memories of getting up and escaping my crib*), and I was tested in a time-free environment in the 1970s and discovered that my natural circadian cycle was, at that time, 32 hours. That's not outlier territory but it's also not very close to the 24-hour celestial cycle**. One of my best experiences with sleep was when I was on a week-long wilderness camping trip and my entrainment got perfectly in sync with the sun—marvelous. 

Last night was almost as good. I got to sleep on time, woke up at the alarm for both awakenings, and got a little more than eight hours total sleep.

To put that in context, back when I was sleeping "normally," that is, trying to sleep all the way through the night all in one go, I probably managed a normal night's sleep of seven or more hours at one stretch maybe three times a month. At best. I never kept records, but I'd bet my car that there were numerous months when I didn't make it to seven hours even once.

As far as the writing time is concerned, it's just marvelous. I love the three-hour "mini-day" (as reader/commenter AN dubbed it) in between sleeps. It's so peaceful and quiet. I can really concentrate. The three hours just melts away every night, and I definitely need the alarm (the alarms are on my iPad, which I bring downstairs with me) to signal me that time's up. At 5:00 a.m. this time of year, the birds are beginning to chirp (serving as an alarm themselves) and dawn is just barely lightening the sky. I'm working on a piece called "Autobiography is Painful" currently, which should end up at about 10,000 words.

The imperative
Writing takes discipline. Consider this passage from a recent article about crime novelist Elmore Leonard by a writer I admire, Anthony Lane:

By 1950, [Leonard] had graduated from the University of Detroit, married a woman named Beverly Cline, and found a job at the Campbell-Ewald advertising agency. By 1955, he had three children and a daily routine to match, as [Leonard's biographer C.M.] Kushins reveals:

Up at five o’clock sharp for two hours of uninterrupted writing (still two pages completed before putting the water on for his morning coffee), then showered and suited for the office—ready to wolf down breakfast and help Beverly feed Jane, Peter, and infant Christopher—then receive the Eucharist during eight o’clock Mass. Finally, he arrived at Campbell-Ewald by nine.

The sheer discipline—“the perseverance to just sit there alone and grind it out,” Leonard calls it—is striking. (Forbidding yourself a first cup of coffee or tea until you’ve written a certain amount, despite not being technically awake, is a brutal habit that I’ve stuck to for decades. Turns out I’ve been taking orders from Leonard all along.)

If I'm going to continue with a biphasic sleeping schedule, and use the time constructively in the service of "grinding it out," I'm going to have to be disciplined in three main ways:

1. Getting upstairs on time
2. Sticking to writing, and nothing but, during the mini-day
3. Stopping writing right on time and getting back upstairs to bed

It's been a fun experiment. Will I continue with it going forward? Constancy is not my best thing. Time will tell. Next update? Eleven months from now. That will be one year from when I started this on June 15th, 2025, nine days after Butters died. Feel free to remind me if I forget.

*I have many detailed memories of very early childhood, including before I could walk, and I was absolutely astonished when I first learned that most people do not.

**"Night owls" are people whose natural circadian cycle is more than 24 hours, "larks" people whose natural cycle is less than 24 hours. The average is about 24.2 hours. 

P.S. How you can tell the illustration is AI-generated: look at the brickwork, especially above the mantelpiece, and the back right leg of the nightstand, mainly. There are a few other anomalies, but those are the easiest "tells." Pretty decent for one try, though.
