I'm new here because I recently found out my vitamin D levels are low. The Dr. didn't tell me the number but I'm on 50,000 IU once a week. I'm only into my 3rd week on this but I have finally had a few nights where I can actually sleep more than 4 hours. My symptoms pretty much match most of what I have seen here. Is there anything else I can do as far as diet or other meds to cope with these miserable symptoms? Dizzy, brain fog, vertigo, ringing in ears, muscle pains with a burning sensation,muscle spasms,random sharp pains all over my body, EXTREME fatigue and anxiety that I may have a disease. When the Dr's office called they said my blood test came back fine with the exception of very low vitamin D. Posts here make me hopeful that I can recover but the thought of a long battle scares me because it has brought on depression and despair.
