Also ADHD here, with a thought that might be useful for you. I am not even a little bit refuting the "non-trivial brain energy to even brush your teeth" bit. That 100% takes brain energy for me. But I would challenge the assertion that we don't have habits. They're just not necessarily the habits we want, but they do get made and broken and exist. As an example, if there's a project I want to work on (getting that motivation is a different problem), I will feel vaguely uncomfortable unless I grab my bag and laptop and drive to a particular coffee shop that's a non-trivial distance from my house. And once I get there, I am generally quite productive. After I eat a meal (remembering to eat is a struggle sometimes, of course), I don't feel "at ease" until I have a cigarette. I've found it slightly useful to not think about habits in the way that the positive-thinking motivational speakers talk about habits, but rather at least spending a bit of time reflecting the things I do when I'm in "autopilot mode". I'm not very good at changing the things I see, but recognizing that they're there has been a bit helpful in tweaking them or at least figuring out why/how they work.
