This is news? Those of us with ADD have been self medicating with coffee for years.

Yep.

I manage to consume 4-500 MG of caffeine before noon most days and am super productive until it really wears off and I have trouble concentrating, downside is if I consume any after noon I have a hell of a time sleeping.

Or worse, as in my case, self medicating with alcohol. In my 20s, it was the only way to calm down and feel "normal". Finally got it diagnosed in my 30s but, thankfully, soon outgrew it and tossed the Ritalin.
