While I applaud applications of the Scientific Method, you write as though you have some doubt that the effects are real. I took Vyvanse for a couple of months to try to help my concentration... holy cow. When it took effect 40 minutes after taking it, I felt like a jackhammer. It was no slight effect that you could dismiss as placebo, my blood pressure went up and I was on task for ten hours of the day, no problem. All the cobwebs that happen after that big pasta lunch? Gone. My mind was sharp, focused, and my friends all noticed that I was noticeably more aggressive in conversation. The down side was that sleeping became very difficult. I'd wake up over and over during the night with way-too-vivid dreams. Worse, my heart started feeling like it was fluttering and my blood pressure machine, which told me that it was a bit higher, also indicated that I had an irregular heartbeat.
