I long ago stopped taking medication for it at all - I don't even have a prescription anymore. I just use coping strategies, many of which are about avoiding situations where it's a problem entirely. I have ADD, and I live with it. Because medication was better, until it was worse.
It really does whenever you have ADHD and you feel like your restless mind is finally at rest. It's absolutely infuriating to be unable to concentrate throughout most of my days.
But when it comes to doing certain things (even things that I like) I can easily talk myself into putting it off until the end of time, but once I finally get started, I usually end up engulfed in it -- at least for that day. Like last week, I wrote no joke... 8,500 words towards scripting out my next dev course in the period of about 12 hours and that was with walking about ~2 miles twice as breaks + meals, etc..
I cycle between hyperactivity and completely unproductive days. Getting up late being the main key to an unproductive day...
