First of all welcome to our forum. Many people with VDD (Vitamin D deficiency) have felt "foggy" headed, lightheaded and some like myself felt like I was drunk all the time. (Unable to walk well, off balance, unable to think straight.) I have both VDD and B12 def. B12 was first diagnosed way before the VDD. (2006??) I am taking every other week injections because I am unable to absorb it well enough with the oral. That helps my extreme fatigue and the tingling I get/got in my extremities.
The VDD deficiency was diagnosed Jan 2010 at my insistence from research done here and other places. Was at 11ng/ml.
I have a strong feeling your D3 (Cholicalciferol) at 1000iu will not be enough to get your levels into the optimum range of 50-90ng/ml range.
1. When will you have your next Vitamin D level drawn?
2. What was your initial level?
Research shows that it can take a year of optimum levels for most symptoms to go away completely. The trick is getting it to that level and keeping it there.
Here is an excerpt from a medical study another member posted some time ago.
Here is a link to this forum where many people listed all the symptoms they were having.
I wish you the best of luck on your recovery. Hopefully it won't take you as long it has for me to reach those optimum levels and keep them there.
BTW you say you are a male, but your profile shows you are a female. You might want to fix that.
