I was 39 when I was diagnosed with adult ADHD. I found an online treatment site, and decided to go with it. I was prescribed adderall. The sad truth of the matter is, if I was given this during high school, I sincerely believe I would have gotten into MIT or another top tier school. I struggled my entire life with concentration issues, giving things the attention they deserve. With adderall, my concentration and focus isses have gone away. Repetitive tasks become fun instead of things to avoid.
My parents, and I don't blame them, were very against psychological and psychiatric help. It's from the generation they were raised. My mother, when I was very young, asked a doctor if I could be ADHD. The doctor asked if I could sit through a movie, which I used to watch Star Wars over and over again. So she said yes and the dr. said I couldn't have ADHD.
It was a game changer. Some things have changed for the worse: I don't have a sex drive now. But as a single man, I don't think it's that bad of a thing. The amount of focus it helps me gather is simply incredible.
It's not for everyone, but I think it was a good idea for me.
