Based on the reviews I've seen, I was hoping for substantial noticeable changes in my concentration and cognition, but I'm on my second week and though I believe mental cognition has improved some, I have no reason to apply it to Qualia and neither is it a substantial improvement. Last week I had some heart palpitations, I think related to the caffeine content, so this week I've reduced my other caffeine intake and haven't had any issues yet.
