* The (largely mental) hyperactivity is controllable, that is, I retain my creative ideas generation and interest in new things, but I am no longer governed by it, and
* The rarely discussed hyperfocus behaviour (which I frankly regard as a superpower) is more easily snapped out of.
To the uninformed, the most paradoxical outcome is that I can take a powerful stimulant medication, lie down in bed, and fall asleep easily, when normally I'd be staring at the ceiling pondering anything from CSS to soldering and unable to sleep for the rush of ideas.
This response to medication is not diagnostic, but it is indicative that the medication I have is correct. Moreover it allows me to both retain the two traits that have made me a successful systems maker, but permits a less chaotic engagement with the neurotypical-oriented processes of modern human society, so for example I renew my passport before it expires.
I self-medicated with a variety of over-the-counter substances for decades, including nicotine, sugar, and coffee. I am super grateful for the medication since I have now dropped the nicotine and sugar.
My psychiatrist believes the condition is a) misnamed, and would be better titled "Attention Difference Disorder", and b) points out that the twin traits of rapid ideas switching and hyperfocus are only a problem in some aspects of engagement with modern society and that in an pre-agrarian society they'd be excellent traits for a hunter.
