It is an amphetamine. Go to r/ADHD and read the thousands of enthusiastic stories of people that just took it for the first time and are basically just high. I took medication for a while and it helped me surmount a bunch of issues. Now I can do well without. I never liked the effect on my body and mind.

The effect doesn't go away, you just start expecting more of yourself. Without medication I was really happy if I could focus 30 minutes in a day, that would have been like a once a month event. On medication I feel like shit if I just got 4 productive hours on a day. So sure not every day is like the first days after you start, but it never goes down to even close the level you are at without medication.
