Kathy, you are very welcome. I hear you, Rachel. After years of critical care work I wake up instantly, but timed light therapy resets your internal clock so you are awake and hungry when you are supposed to be and sleepy at bedtime. They sell inexpensive but dorky blue blocking sunglasses and I even found a portable 10,000 lux light box for travel that is sub powered so you can use the same program to readjust quickly when you fly home. Don't think I'll be posting any pictures of Bert and I in those glasses. Say hi to George.
