This product did not help me fall asleep (took several hours, as if I'd taken no aid at all). However, once I was asleep, I stayed asleep until morning. In the morning, even though it was eight hours later, I felt really groggy and drowsy. I would not recommend this product if you have trouble falling asleep--although maybe with a completely empty stomach it'd work better. If staying asleep is your issue, this may be worth it since it obviously had effects straight through to morning.
