It is a good item to use when you have Honestly more than 8 to 10 hour's of sleep available if you have chronic fatigue syndrome. IF, you are a light sleeper and wake up every few hours, this is a great product to use IF you still have 7/8 hrs of sleep available. You will wake rested and ready to go if you follow the instructions. Also, if you don't get enough sleep, you will be groggy and tired for quite some time through the day.
