There are long-acting formulations that can get you through a day. If you want a short-acting med then that’s your call, but I prefer a steady level of stimulation that carries me through the day.
On meds I have to make sure I don’t lose control of my focus. It’s the opposite problem; I need to make sure I don’t lock on too strongly, versus not being able to focus at all. After all, the underlying problem of inattentive ADHD is an inability to regulate focus appropriately. I find it’s a much better trade-off, mind you, but my point is that I no longer need to rely on this roll-of-the-dice “hyperfocus” state to kick in. Especially useful since I rarely achieve this unless there is a panic-induced deadline looming.
