I tried to take one gummy as directed , and I gave it a few nights (4), and it really didn’t knock me out nor keep me asleep for more than a few hours. I then decided after reading a few reviews to take 2 instead. Not that much improvement. I maybe stayed asleep a little longer but definitely not the whole night. No groggy feeling in the morning, though. So overall it’s a nice product but probably not enough for me all the time. I will continue to give it a chance .
