were you taking a lot of vit d and a little of magnesium at the same time. vit d deplees mg and depletion will cause anxiety. otherwise magnesium should cause mellowness. vit d causes also upregs trytophan dehydrog which produces more melatonin and then serotonin in turn which can make you tired etc. also if youre deficient in d then parathyroid will be maxed out and when you take d you might feel weird in the sudden body chemistry change. felt good for me tho
