Has anyone has success with light therapy? I purchased a little blue light box about three weeks ago, have had some success in improving energy/mood and am now noticing my sleep seems deeper, lasts longer. Am hoping that as I get the timing correct, and with more nights of restorative sleep things might continue to improve. I have typically been totally exhausted all day and had really poor sleep at night, waking about 2 a.m., having problems getting back to sleep, or in an out of sleep a lot and always waking up feeling basically as tired as when I went to bed. This was pretty much a constant state. I've been using the light box in the morning, then around noon at a lower setting. Still experimenting to find the best timing.
