Glad you found the articles. I thought this one was the most informative of the two: https://www.psychologytoday.com/us/blog/sleep-newzzz/201805/what-you-need-know-about-magnesium-and-your-sleep

I just got the mag. glycinate from Amazon today and I plan to take 200mg a little before bedtime after taking 160 mg of mag. citrate in the morning. If I experience any issues, which I do not expect, I will dial back to 100 mg at night and see how that does. Best, Hank
