For me glycine helps amazingly. It's an amino acid that the brain needs during sleep. I take about 5 grams in water about an hour before I go to sleep. I'm not sure how much the glycinate in magnesium glycinate has the same effect.

Oddly, it has the opposite effect as sleeping pills on me, it doesn't make me sleep more but I'm more rested when I wake up. It even happened a few times that I only slept 5 hours but still could focus well at work and bike intensively for an hour in the evening, without glycine that was impossible.

At 20 euro/kg I think I'll take it for the rest of my life, and it probably will add a few years to my life.
