Greg Harrington left a comment on an earlier post:
I have had very similar results [fall asleep more easily] from first-thing in morning D3.(NOTE: I have great flexibility in my schedule — I can sleep/awake whenever I want — so I have been most focused on “restful” sleeping.) Differences: (a) My pre-D3 issue was restless sleep (waking up frequently), not failure to fall asleep. (b) The effect of sleeping all the way through the night was definitely immediate–very first night. (c) Also, most days I also wake up feeling more “rejuvenated”. This is not 100% though.
I asked him for details.
Tell me about yourself.
I’ve lived Austin,TX since 07/2011. Kansas City, MO before that. I’m a software programmer. 6′ 3″. 210 lbs. (White male, mostly German, but completely European descent.)
How did you want to improve your sleep?
I want to sleep through the night without waking up 3-6 times in a 6-9 hour sleep. This problem has lasted for 2-3 years. It sort of crept up on me. I go to sleep between midnight and 2 am.
How much D3 do you take? At what time?
I take 50,000 IU between 8 and 9 am. If I forget or wake up later, I don’t take it. This is the product I take: Bio-Tech D3 in 50,000 IU capsules.
Why 50k? It was available on Amazon, and I calculated that to be what you’d get from 75-90 minutes of full-body sunlight. Thinking about Paleo lifestyle…that seemed reasonable. This is a LOT more than most SE people are taking but I wanted to maximize the effect! 😉
Any effects of D3 on something other than sleep?
I often waking up feeling more rested/rejuvenated. But not every day. I tend to feel tired between 11 pm and midnight.
What happened when you started taking D3 in the morning?
