Found an old study on potassium's effect on sleep:
"Potassium affects actigraph-identified sleep.Drennan MD, Kripke DF, Klemfuss HA, Moore JD.
Department of Psychiatry, University of California-San Diego.The present study examines the effects of potassium supplementation on sleep quality and phase, as indirectly inferred from wrist actigraphy and sleep logs, in normal young males on a low-potassium diet. A randomized, double-blind, placebo-controlled, counterbalanced crossover design compared 1 wk of oral potassium chloride supplements (96 meq/day) to 1 wk of identical placebo capsules. Outcome measures were taken from sleep logs and wrist actigraphy. Sleep was indirectly inferred from wrist-actigraph data using a computer algorithm. Potassium supplementation significantly delayed sleep-log-identified Bedtime (p less than 0.001). Potassium reduced Sleeping Interval for both sleep-log (p less than 0.01) and wrist-actigraph (p less than 0.1) data. Potassium significantly increased actigraphic Sleep Efficiency (p less than 0.05) due to a reduction in actigraphic Wake after Sleep Onset (WASO) (p less than 0.05). No effect of potassium on actigraphic sleep phase was observed. Side effects were minimal and not significantly different between treatment conditions. The results may indicate an improvement in sleep consolidation with potassium supplementation. Further studies using standard polysomnography are required to define potassium's effects on human sleep."

Low levels of potassium cause those leg and foot cramps that wake you up in the middle of the night (per my Grandmother lol). She ate a banana everyday, otherwise, she would get those night cramps.

Years ago (I seem to remember), someone here did a post on potassium and how it really helped with their sleep.
This is the end of the thread.
