The thing is, it DOES work... sometimes. But the older you are the less often it will work.
Like, when you're in your teens, absolutely you can fix a screwed up sleep schedule with this sort of hard reset. It'll work 95% of the time, and will still help at least a little bit in the remaining 5% of cases.
In your 20s it will solve the problem about 80% of the time, help 15%, and make things worse 5%.
In your thirties the ratio becomes 50/25/25%
In your forties there's still a chance the hard reset will work, but the odds don't favor it. Something like 29% chance of solving, 19% chance of helping, 50% chance of making things worse, and a 2% chance of triggering a major crisis.
I haven't gotten to my fifties yet, but I can see the pattern.
Currently doing an Insomniac's Gambit. For those of you who don't know, this is when you mess up your sleep schedule badly enough that you attempt to fix it by skipping an entire night of sleep then going to bed at a reasonable hour the next day. Crucially, it does not work
