I have a really hard time falling asleep. Once I'm asleep, I'm out for a solid 8 hours but my mind races at night. Sleeping with the TV on low helped for a bit but I needed to find something else to use for background noise.  I tried this sound machine. For me, the only sounds that helped were the white noise and summer night. The other ones were water sounds or had some type water in the background which poses an issue to someone such as myself who drinks a lot of water before bed.
