Not really enough information to base a diagnosis on and not that I would be qualified to do so, but the thought certainly crossed my mind that the poster might consider being tested.

Unlike other psychotropic meds, ADHD meds have a fairly high success rate and a rapid onset of effective treatment. Pretty much with one dose a person can tell if they are going to work for them or not. For most that suffer it's like night and day.
