I was just recently diagnosed with Vitamin D Deficiency my level was12. I have a 2 part question…I was Rx'd Vit D3 50,000units 3 times a week Does this dosage seem a bit high? Also, I suffer from terrible insomnia. I've read several articles that this deficiency can be the culprit…just curious what your take was on this. THANK YOU!!! Debbie
