Thanks, MrsD. I watched enough of the video to be convinced about taking Vit D. Can I count on Calcium supplements with added Vit D to provide enough? It says 2 caplets provide 100% of rec Vit D.

I'm taking sublingual B-12 500 ZipMelt. (5000 mcg).

Wiz mentioned Provigil. What is it, exactly? I've heard people mention it, but don't understand anything about it.

Thanks, friends, for your responses. Another miracle I was hoping for (by taking vitamins) was that the dark circles under my eyes would disappear. But I've been reading up on them, and it doesn't sound likely. *sigh Too little, too late, I guess.

Funny, my older brother (age 73) has exercised, eaten healthfully and taken daily handfulls of vitamin supplements for decades and he doesn't have the greatest health. And yet, both our parents lived into their nineties with few physical health problems. I guess there's just no guarantees, are there?
