Each body has a unique reaction, so there is no exact answer. However, it’s worth mentioning that Sleepie is not an immediate-effect medication, but rather a natural solution to improve your sleep with continuous and daily usage, so it’s normal if it takes a few days until you start feeling substancial changes. Daily use in conjunction with the app will yield the best results, and you can track your progress day by day to gain a better understanding of how much you’ve improved.
