In conjunction with the symptoms and the background you give (18 years of this), it sounds a lot like an autoimmune disease. Which isn't saying much, I know, and I'm sorry for that. I've got an autoimmune disease (Crohn's Disease) which has a lot of similar symptoms when left untreated. In fact, many autoimmune diseases have similar symptoms and and hard to track down–I too spent far too much money and time going from doctor to doctor and diagnosis to diagnosis until they discovered what I had. Other peoples' suggestions to test your vitamin K and A levels (because of your reaction to more vit D) sounds like a very good step towards treating the symptoms. Please do, too, go out in the sun as much as possible, as this both aids in the processing of vit D and helps to coordinate your circadian rhythm. Good luck.
