Happy Light and invested in some Vitamin D. D is the "sunshine vitamin," the deficiency of which is tied to depression, bone weakness, heart problems, stroke and more. My doctor recommended 1000-2000 I.U.s per day. Supplements can get pricey, which is why I tend to buy mine at Costco or Trader Joe's. For $4.99, I can get a 90-day supply of happiness in a bottle and - bonus! - the softgels are small enough to pass my ultra-sensitive gag reflex test. By the way, Vitamin D is the only supplement my physician recommended for me. She said studies have shown baby aspirin, fish oil, glucosamine and others to be largely ineffective. I will still take magnesium to fight muscle cramps and valerian root to help me sleep. But, I'm about to free up a helluva lot of space in my medicine cabinet!
