How do you determine your "tiredness backlog"? When I am lack sleep, it seems that I have been so for decades (school days etc.), but obviously there's a limit to how much I can get back. (And the official stance on parenthood here is "oh you knew what you were getting into", so... hopeless, really.) And it is really easy to imagine that backlog small or large, there's no measure.
If you want to explore the community more, I recommend reading the Library, checking recent Curated posts, seeing if there are any meetups in your area, and checking out the Getting Started section of the LessWrong FAQ.
