I just got a lightbox! I have used it for 3 mornings now. I don't know when or if I will notice a difference, but I am really hoping this will be a better winter than any I have experienced in a long time. I am, like so many others...so affected by the shortening days. I hate winter in general for all of the constraints on my getting around, but I really think this is going to help with that overwhelming, hopeless feeling I inevitably get at some point during the winter. I think the lack of light just builds and builds in me until I lose it.
