Hm, I suspect that the anxiety zeroing removed the depressive effect of sleep deficits not only i.e. making me depressed, but prepping me to fall unconscious. I just wake up after 6 hours sleep aware that I’m not fully rested but with none of the normal ease of turning over and falling back asleep that comes with that (none of the unpleasantness, though) – it only affects me at the point I’m nodding off, though thankfully the anxiety zeroing has made it easier to sleep in general – I don’t need such absolute insensate tranquility.

So I find myself building up sleep deficit night after night until I just spend an epic 14-hour night in bed
