I don't have any brain damage that I'm aware of. I'm a Software Engineer. I haven't done any genetic testing.
All right, so you want to do programming-work - lots of logic and such.
How do you respond to L-theanine and caffeine? Do you notice anything when you drink coffee? If you do, consider to get Caffeine-tablets - it's still the tried and true original nootropic. Consider getting some compounds to counteract the peripheral effect of Caffeine if you do respond to it - it will help when you take higher doses.
Btw, I definitely think you should do some genetic testing - yes, they're not entirely reliable, but you would find out if you're a slow or fast metabolizer of certain compounds and such - you can even find out if you're a non-responder to Modafinil as well.
IMHO, it would help you, somewhat, to figure out which compounds might have an effect on you.
There's another Racetam you haven't tried as well, btw - FASOracetam. It's somewhat similar to Oxiracetam, but also slightly activating - it was being researched for the treatment of ADHD actually, but it seems like the results were dissapointing in that regard.
