I occasionally suffer from bad sleep and wonky sleep schedule. I have tried melatonin and it has helped sometimes but I don't want to rely on something like that for achieving better sleep.

The best results I have achieved when seeking better sleep is good nutrition, not eating too close to bed, and exercise. Simple as that but thankfully I'm otherwise healthy person. On top of that, I every once in a while do yoga nidra if I happen to not be able to sleep with quite good results at least personally.
