“I just wanted to send your team a huge thank you for this app. I’ve been using the beta for two months and my sleeping pill use has dropped from 6 pills per day to only occasional use. My caffeine consumption no longer gives me heartburn and I don’t have heart palpitations anymore. I can attend family functions and be awake the whole time. It has seriously changed my life. Thank you!” -Sarah
