Besides my dosage question: have you noticed any sleep benefits to supplementing potassium?
I think a general high water high electrolyte diet has benefited my sleep. I haven’t noticed potassium immediately before bed decreasing sleep quality.
Well, I’ve finished ~2 months of data. The Zeo sleep stats say that there is a major negative effect, so I’m going to chalk up potassium as a failed experiment for me:
I also replied on Reddit… but I’m wondering if co-administering magnesium would fix this. Or test if Concentrace (http://www.amazon.com/Trace-Minerals-Concentrace-Mineral-Drops-Glass/dp/B004AC07G6/ref=sr_1_2?ie=UTF8&qid=1356074954&sr=8-2&keywords=concentrace), mostly my favorite commercial supplement and a highly bioabsorbable magnesium, improves sleep quality.

I’ve just finished my followup experiment: http://www.gwern.net/Zeo#potassium-morning-use
I standardized a smaller dose, blinded consumption, and took it immediately upon awakening. The negative effect was much smaller (as expected) but there was still no apparent benefit.
