content: This is an excellent sleep aid. Although my sleeep problem had not been fallng asleep, I find this CD helps me fall into a deeper sleep. Although I have experienced periods of wakefulness during the night, using this CD has meant that the wakefulness is far less. I went from 40-50% wakeful to 5-15% wakeful. It is very seldom now that I get out of bed during the night. Highly recommended.
