I only took Calm Thoughts a few times and did not have any luck with it. Each time I took it, I became irritable and found it incredibly hard to stay in one place for very long as I felt a bit stir crazy. I was not productive, I more just would feel anxious and focus on what I wasn't getting done. I see other reviewers have had great luck with this product though.
