@freemo Admittedly, it is a bit hard for me to function, if I have been lost in my work for too long.
It came across as stupid. We were working on a paper together. I had to put two sections of text right next to each other so I could remember one section long enough to adapt it over. And at the same time they were giving me lists of tasks, and random questions. Probably not a reasonable situation late at night without coffee. But it felt odd because they were handling this much bandwidth just fine. I was not.
@jmw150 Generally ADHD, at least in my expiernce, should increase your bandwidth not decrease it (if you manage it of course). Where I find people with ADHD have trouble is where the bandwidth is narrow. In other words if your asked to focus intently on a single boring task for extended period of times (low bandwidth) it can be very difficult. However when given a dozen tasks to handle all at once someone with ADHD can juggle them quite well usually.
If you had been assigned multiple tasks when you found yourself struggling with the one you suggested you would have just put it aside and worked on a different task for a bit, then once your in a more receptive state of mind move back to the original task, perhaps doing it in short sprints rather than all at once.
I find when people with ADHD follow the above pattern they can excel at their productivity beyond that of someone without ADHD.
