I recently purchased this and found it to be very effective.

My entire life I have had an experience with sleep where, when I wake up in the morning, I feel worse and far more tired than when I went to bed. It is as if only a moment has passed and it's already time to get up. I have found things that can change this experience--substances that allow me to 'feel the passage of time' while I sleep, making it feel like I have actually slept, and allowing me to feel more rested. The problem has always been that such substances are inconsistent, at best. This is the only product containing calea zacatechichi in a viable and trustworthy form that I have been able to find, and it works like a dream--which, yes, it does seem to induce. I personally pair this with lion's mane mushroom and a few other sleep oriented supplements right before bed, and I have had amazing and consistent results. Often, one of the problems with supplements is that they lose their effectiveness over time. I've been taking this daily for a couple of months and it has maintained its effectiveness every single night. As someone who has invested themselves in finding supplements that deliver real results, I would easily place this on a top ten best finds list--possibly top five.
