I had huge issues falling asleep. I was unable to fall asleep before 1am and had to get up at 6am. So Monday - Friday was a downward spiral of sleep debt and all of stresses that come with that.

I eliminated blue light (mostly) after 8:00 and it help slightly but within the margin of error.

I then added 15 minutes of mindfulness meditation everyday at lunch. Nothing wooy just mindfulness.

Within 2 weeks i was naturally getting tired around 10:00 and able to fall asleep in less than five minutes.

Quit meditating (because its a pia to find the time, it shouldnt' be but it is) and sleep problems returned.

I didn't even attribute my sleep improvement to the daily practice until i noticed my sleep was all messed up again.

It works and its just 15 minutes. People's millage may very but it was life changing for me.
