I used to use stimulants (legally, and with a prescription, if there's any doubt...) and would seriously consider going back on if I had medical insurance and could afford it. I'm not ADHD, but I have a lot of memory problems and felt more like a neurotypical person on them as well, which definitely helps me function in the real world.
If you get bad side effects, or feel too jittery on stimulants, you can try a slow or extended release format. That usually solves a lot of the problems, especially for people who are sensitive to drugs.
