I'm 30, had a severe Traumatic Brain Injury two years ago, and my doctor worked and worked to get me to try it. I have a huge aversion to drugs. I didn't do it for a long time, but I finally agreed to a one week trial. The results are ridiculous. How it changed my life.
Focus: I used to have great focus. I could multi-task no problem. After, no way. Adderall made it so that I could relate "point a" to "point b" and that all to "point z." Without it, a speaker would say something, and it'd be pointless because I couldn't relate it to anything without *extreme* effort.
Processing Speed: When a speaker is saying something, it requires much less time to process it all. My economics teacher was like, "The more a progressive tax rate goes up, the more that the actual tax percentage paid *also* goes up, but it's always behind the rate that the newest income is in." Without Adderall, I would have had to hear this two or three times out loud to make any sense. I would have to write it down and think on it for a second for maximum effect. With Adderall, I'd get it on the first go-round.
Patience: My wife says that I have much more patience when I'm on Adderall. Patience with her, the kids, myself, and my taskload. Before, I'd start snapping sooner. Now (according to her) I'm much more willing to hear it all out before I make snap judgment.
Confidence: I have much greater confidence to start a new task. I do the task without the hesitation that I had before. I'll tackle big projects and get them done quickly without having them take all day/afternoon.
Not saying you have a TBI. I hope you don't. But some of the probs might be the same. If you see an issue above that you are also having, it might be worth it to try it out. Just do it legally.
