I try to get to bed by 9:30. I don't often make it until 10. I use a black sheet at my window held with towel grippers glued to the wall around the windows. It works really well. I am very light sensitive when I sleep at night and am up with the first ray of light the next morning.

Vitamin D therapy has been working great for me but my requirements are now at their highest, probably for the rest of the winter. After being without cravings for carbs for so long, they subtly sideswiped me. Now I'm trying to find how much I need and how to take it without forgetting a dose. That extra dose is making and is going to make the difference in my mood and carb cravings. I know it.

Vitamin D taken less than 4 hours before bed prevents sleep. You aren't wired. You aren't restless. You're just too alert to sleep deep. You can rest and even doze but you sleep very lightly. That's been my experience and the general experience of others that I know that are taking the D.
