I love this stack! When I dont have this product I can tell something is missing. The PM is great, helps me get to sleep and stay asleep. But it isn't like other night time products I've taken. When I get up in the morning I am right awake. No sleepiness or trouble getting started, I feel focused and ready. Taking the AM just keeps that feeling rolling throughout the day. I noticed this product also has 5-HTP, which helps pick my mood up. I've not only recommended this to friends and family, ive purchased and gave away 4 stacks. Thats how much I believe this product will help people!
