Been taking. 50000 iu vitamin d for 3 months. Lately feel very tired stopped oct vitamin d. Should I go to ER bc I also feel "off" mentally?

DON"T GO TO. The er for such a minimal complaint. It's a waste of money and health resources. Talk w/your doctor. That's what they're for. Your symptoms are not due to the vitamin d, although i don't know your dose since i don't know how often you were taking it.
