I'm really curious if insomnia or DSPD counts as a sleep disorder here.
I guess the core point of the study is, if you force yourself to be on a morning schedule for a few weeks and follow basic sleep hygiene, then it will work and you will feel better.
I don't know what to take away from this. I already follow their protocol, but my sleep onset is still naturally around 1:30am. For me, when I go to bed earlier, I fall asleep even later than usual, since I just doze for an hour and am even more awake. When I wake up earlier, I tend to fall asleep during the day. (I test negative for sleep apnea).
The comments here are pretty split between "I just tried getting up earlier and it worked great!" and "I do all of this and it doesn't work at all," so my experience isn't unusual. It reminds me a lot of comments on anti-depressant efficacy.
So I'll probably do the same thing I do every time a study like this comes out: Follow the sleep protocol more carefully for a few weeks, then feel discouraged when it gives no results, then feel even worse from the comments claiming that I am just being lazy. And then finally I will remember that the science on this subject is weak and incomplete, that morning people's unyielding sense of righteousness and morality is based on nothing, and that maybe someday we will discover universal methods of adjusting sleep schedules.
