About 3 weeks ago, it was determined by blood test that he had a
vitamin d deficiency, and his doctor put him on 50,000 iu of
vitamin d per week. Very gradually he has started to have extreme anxiety, and trouble sleeping. This is something he has never had before, and it is very baffling, he is not under any particular stress. He had his thyroid checked yesterday with a blood test, and the test came back normal. Any suggestions?
