I’ve always been a light sleeper, and have had terrible problems falling and/or staying asleep since having children over 12 years ago. I’ve tried pills, pillows, counseling, meditation, music, boring audiobooks, etc with only fair success at best. I also rarely pay for apps, and this is the most expensive app I have ever bought! But I was desperate to get some decent sleep. At first I wasn’t successful with Slumber, but after trying different things Slumber offered, including things that I didn’t think would work, it’s been great! I usually fall asleep fairly quickly, and even better, when I wake at 3 am, it gets me right back to sleep (rather than be awake for 2 and 1/2 hours and then have to get up at 6:00 like I did for years). It’s not perfect 100% of the time, but it is by far the best “sleep aid” I have tried.
