Methylphenidate
"I am 37 years old and was finally diagnosed with Adult ADHD almost 2 years ago so I was put on 20 mg Adderal XR and it worked great. But I did start to notice that I would get pretty irritable on it mostly when it was wearing off. So I wanted to try a different medication to see if there was one I wasn't so grumpy on. So I started Metadate CD and I was not irritable on that one at all :) But it seemed to wear off within 4 hours and made me soo tired. So now I am on Aptensio and it has been pretty good so far I have only been on it for about a week and it really does last a long time and I am able to stay focused. I don't feel a crash like Adderal. I would just recommend taking it early in the morning so it can wear off before you go to bed."
