I have low vitamin D and hear that this can cause D. So, the doc tells me start 2000 iu/day (split dosage) supplements and come back in 2 months to see what my levels look like. OK. But, a month later I don't feel any better. If anything, the D is worse (cramping-wise, too). Still have the fatigue, fuzzy-headed, crappy all over feeling that I saw him for in the first place. Any ideas? By the way, I'm supposed to be taking iron, too, but it makes me stinky so I don't. And I never saw a difference when I tried LNape's calcium treatment--and I am very disciplined for treatments, gave it a solid 2 months before saying I saw no results. Keep a journal w/ daily entries, so I can record and go back to see thoughts and physical symptoms, food diary, etc. Also, I have a family history of thyroid, but he says that's okay. What say you all?
