I have suffered from depression for many years and after trying several different antidepressants, I finally gave up on them. My sleep had become terrible. I would toss and turn for hours and wake several times during the night once I did fall asleep. I started taking Belsomra, which was very expensive. When I saw an ad for FW stimulator, I took it too my Dr and he said to try it and wrote me a prescription. I thought it was well worth the money if it works. I have been using it since last fall and my sleep has improved tremendously. I fall asleep easily and stay asleep. If I do wake I fall right back to sleep. I even dream, so must be getting better quality of sleep. I quit the sleep medication right after starting with the FW. My depression has also improved. I would definitely recommend this device. It is worth the money. It is less expensive than antidepressants or sleep medication!
