D3 for Insomnia
Kathi (New Brunswick, NJ) on 02/07/2009: I developed severe insomnia last winter (nov 07) and went through quite a trial for months, with none of the many things I tried helping much except some tips on how to improve sleep habits through cognitive behavioral therapy. I was doing better May-Oct 08 then all of a sudden the same severe insomnia symptom was back in full force. Last month I decided to try vitamin D3 2000 IU/day, after reading so many recent articles about the importance of this sunshine vitamin. I chose tablets with D3 source from lanolin, since I am allergic to fish. Within a week I was sleeping soundly at night, and I am continuing to sleep well. In retrospect, it is likely that I became more susceptible to vit. D deficiency after I became lactose intolerant and stopped drinking milk.
