Does anyone use one of these? They wake you up slowly in the morning? I heard a psychiatrist talk about these for bipolar and wondered if it might help. In the summer, when the light comes in the window I bounce right out of bed and cannot sleep in usually. I need less sleep and wake up energized. In the winter I can barely get myself up because it's still dark outside. I already use a light box sometimes, but might get one of the dawn simulators, too.
