The personally confounding thing was that I assumed there would simply be a withdrawal period and I would start to feel normal at some point. That never really happened, even years later. After hearing rumors I started looking at articles like this https://www.scientificamerican.com/article/do-adhd-drugs-tak... and this https://www.acnp.org/g4/GN401000166/CH162.htm and I started to think that perhaps taking these drugs as a child over a period of 8 years might actually have had a much deeper impact that I realized and after trying various things over the years I found some that seemed to help. The causality was a little funny. I started lions mane, it helped. Herbals usually don't do much and I started doing research into why it might help so much. Lion's mane increases nerve growth factor, and that led me down the rabbit hole.
