If I completely buy Guzeys citation, sleep deprivation works for half of people temporarily. So, kinda useful but not sustainable. It also ignores memory and other effects sleep has on mood.

The point I am making is we can keep throwing new treatments at depressed people, or we can finally recognize the immense heterogeneity of depression, in both its genetic & environmental causes, as well as its many phenotypes (there are lots of ways to hit the inventory threshold). This fact is why this argument over sleeping or not is even happening. It’s not a tangent, in my opinion. This is the central problem.
