I am new to the group. Just found out I am Vit D deficient - 16. I am taking 50,000 iu's once per wk for the next 3 months and then go back for a re-check.. Just took my second pill 2 days ago. First week I thought I felt a little better, The last two nights have been worse. The leg cramps have kept me from sleeping much. My symptoms are: calf, toe, jaw, finger cramping, bone pain, numbness in my feet, balance problems, muscle weakness, tiredness, and depression. I have felt bad for years and stopped complaining about it for a very long time. Only my husband knows how I have felt. I'm amazed at how supportive he has stayed. How long does it take to recover? Thank you in advance for your support. Ev
