    Wow, the timing of this post is weird! I've been taking 5000 daily for almost a year. I always take it in the morning but my sleep has been just awful. This morning as I was getting ready for work I decided I should google sleep issues with vit d and see what I found. I haven't had time to do a search yet but it appears there may be a link from these other responses. Not sure what I can change since I already take it in the morning but I guess it may be enough to know why I'm having troubles sleeping.

    You could try dropping the dose. 4000 is the rda in the UK.

    Thank you comptoneliza. My dr put me on it since I was so low. I'll be getting re-checked soon and hopefully I can lower my dosage!

    Yeah, 5000 is above the suggested limit of 4000 in the U.S. Maybe the doctor will lower it.

    It's a shame because I've definitely had more energy since I started taking it but I cannot deal with the Insomnia!

    Drs prescribe 5000 all the time in the NE. We dont get much sunlight for 9 months of the year.

    Thanks for the input everyone. I guess it's just as we all knew...everyone is different! But I've gone back to taking the D3 in the morning again and my sleep has improved. I'm also very close to dropping my dosage down from 5000 IU to 1000 IU because the deficiency has been corrected now. I'm hoping that will make any sleep disruption go away entirely.

    I'll probably try 5000 in the late afternoon or evening one more time though, just to see if there is an effect.

    The suggested limit assumes either 4 or 6 hours a day of time outside.

    OTOH, Yes, if your D3 is properly balanced, you will have to adjust to less sleep and more energy. That's not necessarily a bad thing.

    This is true! I guess as a chronic Insomniac I tend to be obsessive about the amount of sleep I get - on a good night I rarely get more than 6 hours and vit d reduced it drastically.
