“Zeo Sleep Self-Experiments § Magnesium Citrate”, Gwern2010-12-28 (, )⁠:

EEG recordings of sleep and my experiments with things affecting sleep quality or durations: melatonin, potassium, vitamin D etc

Re-analyzing data from a magnesium self-experiment, I find both positive and negative effects of the magnesium on my sleep. It’s not clear what the net effect is.
