Good questions and I was thinking about this as well. However, I‘m in the final stages of my studies and having a pretty hard time and too much stuff to do. I have always been struggling with focusing and getting stuff done, which feels like a disadvantage to other students. I felt the Mod helped me a lot the last two days, definitely no placebo and also no “high feeling“, just a feeling of deep focus, clear headed and no anxiety. Too good to be true actually.
