So today is day 3 of being on celexa, which I'm doing a lot better. I haven't had a panic attack since Saturday. Today I got my blood work back. I have a vitamin D deficiency and my white blood cell count is a little elevated. My doctor prescribed me vitamin D capsule's. I picked up and came home to take one. Now I'm feeling a little weird. My heart raced a little and I didn't have a panic attack but just made me a little anxious. The dose seems high but my vitamin D level was really low. So I'm thinking that may be why. Has anyone else taken just vitamin D with a really low count? I tried not to read the side effects but I caught a few on the packaging and I think that may have triggered some anxiety.
