Jody, I tried this "gentle" version out for the first time last night. Wow is all I can say. You just have to experience this once to know that you are not sleeping right. I still have to figure out something with the headphones, as I am a side sleeper. My in-ear iPods did stay in for the full cycle though but are not that comfortable. I had no awareness of time. I fell asleep and woke up 90 minutes later. Felt like a split second, but I felt more rested than a full night sleep previously.
Awesome! For side-sleeping, check out headband headphones like these "CozyPhones"... https://amzn.to/2TcdGaK
