I tried the full spectrum light - it gave me freckling and my opthamologist was not happy that I was using it - he could not endorse that it was not harmful to my eyes -- something to consider!!!! I tried Wellbutrin for 2 winters, if it helped it seemed like the placebo effect (not much help) this summer my MD put me on Vitamin D (Ergoclaciferol 50,000 units one capsule per week). He put me on it after testing my blood vitamin D level which was low normal. I am on it for my osteoporosis, but doc says this type of vitamin D therapy is now linked to prevention of colon cancer and other chronic illnesses. All I can say is that my SAD has never been better! It is fabulous. My doctor was puzzled, but I am a believer! Tokie
