I have had difficulty sleeping forever but this difficulty developed into insomnia over the past three years. Medications worked, but left me feeling lethargic and drowsy the following day. I have been using the FW device for three months and it has enabled me to develop healthy sleep patterns, to get more sleep, and to be able to return to sleep if I have woken up at night. I am currently under tremendous pressure( an international move) and managing the stress well thanks to the sleep the device has enabled me to get. I highly recommend the device. Use it regularly and follow the directions.
