Ohhhh, I've heard of that! It's like the opposite of typical Seasonal Affective Disorder, where your highs are in the winter rather than summer. I've heard of people having to black out their windows and use ice packs to get relief. (I'm sometimes morbidly interested in abnormal psychology. It's a coping mechanism.) On a somewhat related note, has anyone else noticed how many mental disorders are abbreviated SAD? Seems ironic.
