I can NEVER sleep at night, probably due to the fact that I'm on the computer all day, but this product really works for me. The Snoozeberry flavor is my favorite but it can be a little gross if it's room temperature. Make SURE you put it in the fridge and it will taste yummy and refreshing. It makes me slowly get sleepy and not exhausted. I usually take this about 30 minutes before bed and it truly does help me fall asleep easily.
