Yeah this is probably not too far from my daily routine, except replace coffees with energy drinks. Though I oversleep significantly on the weekends (normally aided by the effects/after effects of shit that’s worse for my brain).
It very obviously has major negative effects, but I just can’t bring myself to change it. I’ve tried once or twice, but I always return to this.
If life was a little more flexible, I think I could pull off biphasic sleep and be ok, but when I want to sleep I usually have meetings and when I’m wide awake it’s usual the middle of the night (writing this at 3:25am).
If you don't you're going to have burn out. not just emotionally but physically.
I had a fit that the Dr put down to poor sleep and eating habits. It took me weeks to get over the immediate effect of the fit, I felt like I'd been worked over with a baseball bat.
I used that recovery time to go cold turkey on caffeine (if I'm going to feel like crap i might as well have a good reason for it), I limit myself to tea only now, and only 1-3 cups a day. I eat a lot better and I go bike riding a few times a week. I get at least 6 1/2 hours a sleep a night, and aim for 7-8.
its worth noting that while there is evidence for sleep debt, there is no evidence that oversleeping helps correct it.
either that or 47 is "wind down time" for my brain
