So true! I suffered with insomnia and hot flashes for months until I happened to start taking Vitamin D3 for anxiety. I take 5,000iu per day starting with a loading dose of 30,000 the first day, and within a week NO more hot flashes and sleeping through the night. Absolutely astonished Vitamin D3 could help me sleep this well. ALWAYS take in the morning either with or without food, never take it at night because it's initially very energizing.
