Thanks Mark and MRH The nutrition aspect makes a lot of sense to me right now. A couple of months ago I was diligently taking a multivitamin as well as a b complex supplement, and I didn't feel this way. I was also eating a lot better and I was exercising. In the beginning of August I had exacerbated symptoms for a couple of weeks after going to the beach (sunlight does me in) and took some time off from the gym, then my diet regimen fell apart as well. I did have some bloodwork done at the doctor. Everything was normal (including thyroid levels) except the vitamin D levels which were low. A retest after 3 monhts showed that my level is now normal.
I really hate taking pills, so I will try the diet/vitamins/exercise route before asking the doctor about any other medication.. Thanks for the advice
