While it doesn't leat to the good sleep, it helps me trigger the 1-3 hour sleep quite fast.
Luckily, my standard sleep is getting a lot better lately.
Instead of alarm clock at the correct time each day, I am at the stage, where I can put the times alarm, and fall asleep a bit sooner. But it has to be a timed one, since a single 10h sleep would fuck the whole thing up.
