[Margaret Pilkington]

I don't feel sad.........when I am affected I just feel tired, and hungry for carbs.(I test my own sugar levels)

I know that bright light does make me feel better because the winters(their summer) we spent in Oz (coming back late March) I was not affected. And the last couple of years when we had snow on the ground for longish periods, I was better too(reflected white light even on grey days does help).
It is the lack of energy that bugs me........I want to get up and go, but I feel like I'm wading through treacle.
