Can you find out your level? And the units used to measure? ie 40 ng/mL or 40 nmol/L? Lab 'norms' don't mean much but specific numbers can tell us alot.
Same for your calcium numbers.
If you truly are hypercalcemic you really can't supplement extra D until you figure out why you're hyper calcemic. I'd want more info regarding parathyroid hormone levels. it's worth considering.
