A nurse in line at the DMV told me to stop taking my vitamin D at night, and my sleep tracker proves she was right
I was renewing my license in Phoenix back in March and this older woman behind me noticed my pill organizer when I pulled out my wallet. She said she was a retired nurse and that vitamin D can keep some people wired if you take it too late, so she always told patients to move it to the morning. I figured it was nonsense but tried it the next week and my tracker showed me falling asleep 40 minutes faster on average over 12 days. Has anyone else had a supplement mess with their sleep like that, or did I just get lucky with the timing?
