(Mild ADHD here) Hyperfocus sounds great, yet it comes at a steep price: extreme exhaustion. Sometimes I just can't work for days (weeks happen) straight. Then at times hyperfocus kicks in and I complete three days work in one swoop, but after that I feel energetically empty. You're right on the dependence because HF gives a high, and I admit although the attention deficit part is a terrible pain, the high is so great that a part of me doesn't want to medicate, because it would go away.
Hyper-focus is not great, nor is it some form of "super power" that adhd people have. Its any time that somebody with adhd is able to focus on something. People without attention disorders can focus willingly, people with adhd cant.
The difference is that the adhd brain is deprived of euphoric dopamine until you have that "hyper focus" activity that the adhd mind begins to depend on.
People with adhd are highly prone to becoming mentally dependent on activities like video games because of this euphoria. However, I find that being medicated appropriately and focusing on what I want to focus on is more rewarding than the activities I depended on pre-diagnosis and treatment.
