I am a 22 year old female and I was diagnosed a couple weeks ago as having extremely low vitamin D levels. My test showed that I was at a 4 and needed to be at 30. I had no real symptoms of this deficiency besides depression and anxiety, but I have an anxiety disorder and depression normally.
My doctor prescribed 50,000 unit megadose of Vitamin D to take once a week. My doctor told me to take it on the same day each week. The morning after the first time I took it, I felt like I had more energy and was happier. Things that would normally have given me anxiety didn't bother me as much. I even had enough energy to go for a mild work-out. But maybe 4 or 5 days later, I felt achy, severely depressed, anxious about everything, was having muscle spasms, and didn't feel like doing anything. Then came the day to take it again. I felt better the next day, had more energy, was in a better mood. And now it has been 5 days and I woke up with a severe anxiety attack (questioning reality, heart racing, hot flashes, dreading feeling, depersonalization, etc...).
I wanted to see if anyone else has had these feelings? Or if I should ask my doctor if I can take the vitamin D more than once a week? How long does it take until you feel better all the time and not just a couple days after you take a mega-dose? Is it because my level is so low that my body feels like it is in withdrawal when the mega-dose wears off?
