It's been almost a year since I last posted. I guess it's true that you tend to take your health for granted. Fortunately, I've had the luxury to do so this year. I'm glad to report that ever since I started the D3 regimen I've been completely pain free. No more headaches, and not just CH. I don't recall having any kind of headache in almost a year. I've been thanking God and the fine people of this site that directed me to this regimen whenever I can. To those of you still undecided, please give the D3 regimen a chance and stick to the guidelines. And to the people on this forum that helped me, from the bottom of my heart, THANK YOU.
