being a night owl is not good for your health for a lot of reasons (I am one).
It is better for me to align with a pattern where I get some level of restful sleep, as opposed to one where I do not ultimately.
In an ideal world, you are obviously correct, but in the world between a severely disturbed sleep where I get a handful of hours of actually restorative sleep, vs once where I actually sleep for 7 hours? One wins over the other.
And yes, given I have an entire medical team (for other reasons, I have a SCI) I have done about everything you can to resolve sleep. Between ADHD however, symptoms related to the SCI etc, we really do just have to go with whatever we can reasonably get.
