question: Dear Dr please help I feel so rough in the mornings, my head is heavy I just want to go back to sleep but I have to push myself. I find it hard to think clearly and have to fake it that all is well. The foggyness has gone from my head by the afternoon and I feel human. I was thinking could it be SAD as the feeling is worse in the winter. In the heart of summer I don t feel so bad. But I have notice the symptoms have reappeared. I have anemia and take iron tablets. I have cut meat out of my diet 90% as I want to eat as healthily as possible and I believe that a vegeterain diet is the most healtihest. Please help me.
