Yep...

I was thinking your prescription meds or an OTC med might be the real culprit.
Too much, too often or not appropriate at all.

Many times vitamins take a long time to really make their way into your system or to make a difference. I suppose taking several different things at once could also make it a little confusing.

If you have signficant energy problems, try not to take any medications that are sedating or ask your doctor if you can keep the dosage very small.

And if fatigue continues to be a problem, you might have to try a variety of different things to get it under control...vitmains just being one piece of the puzzle.

Wishing you well.
