I don't know if I'm highly intelligent. I'd like to think so but I also feel like I'm really good at cheating the system. I can learn the basics of stuff really fast and then bullshit through while I slowly pick up more advanced things.

I've tried adderall but it almost became a game to see if I could beat it. I would procrastinate even more than normal. Sometimes just stating at a wall for hours at a time

There are other drugs.

I was diagnosed with ADHD a few weeks ago. So far I've trialled ritalin and dexedrine.

Ritalin works very well if I have a clear task.

Dexedrine made me tired, confused and aggressive.

The point is: different drugs work differently for different people. Trial different ones. There are even drugs that have non-stimulant modes of action now.

Hmm, try just an NRI (http://en.wikipedia.org/wiki/Norepinephrine_reuptake_inhibit...) - it may help you focus and give you energy without getting stuck or obsess over things (i.e. without the dopaminergic effect).

ADHD is NOT add .. big difference and distinction to be aware of.

ADD is no longer used as a medical term. It has been subsumed into ADHD, and the distinctions of predominantly inattentive, predominantly hyperactive, and combined were created.

It is very common for people with high IQ to go through their entire academic lives undiagnosed, and only as adults, when sheer intelligence isn't enough to pull them through, they realize they need help.
