That's interesting about the Vit D Mrsd and I thank you for that.

My neuro checked my Vit D level last year and found it quite low so I've been taking oral supplements ever since. I also started Actonel a few month ago for osteoporosis and that came with Vit D, so even if I wasn't already on it before I'd have to take it now with the bone meds.

I haven't taken Vit B in any form for a number years, but that's something else I could look into.

I'll look at the site you suggested but I'll hold off on the Efexor for now. I really appreciate you taking the time to reply to my question, and I thank you very much.
