Vitamin D3 fucking me up?

Fellow long haulers,

Has anyone here had an adverse reaction to taking D3 + K2 supplement? My blood test recently showed I was slightly deficient so my doc prescribed supplementing. I started taking 5,000iu per day yesterday and after my dose today I am experiencing a heightened dizziness, heart rate and manic type feeling, blurred vision almost exactly an hour after I took it. I had to cancel my 3 hour gig even though I was pacing great this morning and feeling good enough to go. What gives?
