I started taking Vit. D3 about 3 weeks ago - 5,000 IU, once in the morning. It took me about a week, but my depression slowly started to lift. Once it came up a little bit, I took to making sure I made it out of doors and into the sunshine at least some part of every day. Some days this is a walk in the morning with my son, others it's taking a 10-minute break from work and standing outside on the patio. Just yesterday, I realized that I might be feeling close to what baseline must be for me. I bit jittery and some anxiety, but totally manageable. I don't know if it's directly attributable to the Vit. D3 or not, but I'll continue to take it.

I also just had a blood test last about 10 days ago and got my results yesterday. My D level is optimal now (don't know if I was deficient before - chances are good). I'm on the low end of the optimal range, but still in there. For now, I'll continue to take the D3 supplement.
