To be diagnosed as an adult, you also need to have had it as a child. ADD/ADHD is not something that typically has an onset in adulthood.

Regarding stimulants, if they don't make you hyper, and they DO increase your focus, that sounds helpful, but it doesn't necessarily mean that you DO have ADD. You might be depressed, and the stimulants help the cognitive aspects of depression.

Either way, whatever works, right?
